WHY TO VISIT TEMPLES ???

Believe in science not the crap....
 

Scientific Reasons behind visiting temples :

There are thousands of temples all over India in different size, shape and locations but not all of them are considered to be built the Vedic way. Generally, a temple should be located at a place where earth's magnetic wave path passes through densely. It can be in the outskirts of a town/village or city, or in middle of the dwelling place, or on a hilltop. The essence of visiting a temple is discussed here.

Now, these temples are located strategically at a place where the positive energy is abundantly available from the magnetic and electric wave distributions of north/south pole thrust. The main idol is placed in the core center of the temple, known as "*Garbhagriha*" or *Moolasthanam*. In fact, the temple structure is built after the idol has been placed. This *Moolasthanam* is where earth’s magnetic waves are found to be maximum. We know that there are some copper plates, inscribed with Vedic scripts, buried beneath the Main Idol. What are they really? No, they are not God’s / priests’ flash cards when they forget the *shlokas*. The copper plate absorbs earth’s magnetic waves and radiates it to the surroundings. Thus a person regularly visiting a temple and walking clockwise around the Main Idol receives the beamed magnetic waves and his body absorbs it. This is a very slow process and a regular visit will let him absorb more of this positive energy. Scientifically, it is the positive energy that we all require to have a healthy life.
Further, the Sanctum is closed on three sides. This increases the effect of all energies.

The lamp that is lit radiates heat energy and also provides light inside the sanctum to the priests or *poojaris* performing the pooja. The ringing of the bells and the chanting of prayers takes a worshipper into trance, thus not letting his mind waver. When done in groups, this helps people forget personal problems for a while and relieve their stress. The fragrance from the flowers, the burning of camphor give out the chemical energy further aiding in a different good aura. The effect of all these energies is supplemented by the positive energy from the idol, the copper plates and utensils in the *Moolasthan*am / *Garbagraham*. *Theertham*, the “holy” water used during the pooja to wash the idol is not plain water cleaning the dust off an idol. It is a concoction of Cardamom,*Karpura* (Benzoin), zaffron / saffron, *Tulsi* (Holy Basil), Clove, etc...Washing the idol is to charge the water with the magnetic radiations thus increasing its medicinal values. Three spoons of this holy water is distributed to devotees. Again, this water is mainly a source of magneto-therapy. Besides, the clove essence protects one from tooth decay, the saffron & *Tulsi* leafs protects one from common cold and cough, cardamom and *Pachha Karpuram* (benzoin), act as mouth fresheners. It is proved that *Theertham* is a very good blood purifier, as it is highly energized. Hence it is given as *prasadam* to the devotees. This way, one can claim to remain healthy by regularly visiting the Temples. This is why our elders used to suggest us to offer prayers at the temple so that you will be cured of many ailments. They were not always superstitious. Yes, in a few cases they did go overboard when due to ignorance they hoped many serious diseases could be cured at temples by deities.

 When people go to a temple for the *Deepaaraadhana*, and when the doors open up, the positive energy gushes out onto the persons who are there. The water that is sprinkled onto the assemblages passes on the energy to all. This also explains why men are not allowed to wear shirts at a few temples and women are requested to wear more ornaments during temple visits. It is through these jewels (metal) that positive energy is absorbed by the women. Also, it is a practice to leave newly purchased jewels at an idol’s feet and then wear them with the idol’s blessings. This act is now justified after reading this article. This act of “seeking divine blessings” before using any new article, like books or pens or automobiles may have stemmed from this through mere observation.

Energy lost in a day’s work is regained through a temple visit and one is refreshed slightly. The positive energy that is spread out in the entire temple and especially around where the main idol is placed, are simply absorbed by one's body and mind. Did you know, every Vaishnava(Vishnu devotees), “must” visit a Vishnu temple twice every day in their location. Our practices are NOT some hard and fast rules framed by 1 man and his followers or God’s words in somebody’s dreams. All the rituals, all the practices are, in reality, well researched, studied and scientifically backed thesis which form the ways of nature to lead a good healthy life.
The scientific and research part of the practices are well camouflaged as “elder’s instructions” or “granny’s teaching’s” which should be obeyed as a mark of respect so as to once again, avoid stress to the mediocre brains.

xenos great dane manual remote central locking 2w
Remote control central locks have become common, and most cars today have remote control lock facilities. The main trigger for advancements in car lock systems is the increase in theft rates caused by increase in population which had led to a highly competitive work atmosphere. With remote locks doors and dickeys can be opened with just a click of button. This becomes more convenient than manual locks where car owners will have to spot the lock hole and turn the key.

The Xenos Great Dane remote or manual central lock will ensure that your car is safe at all times. The lock buttons are on the remote itself, but there are circumstances when people forget to lock cars. The risk of car theft is now on the rise, but if the Xenos Great Dane remote lock is safe with the owner, than the stolen car can still be traced through a computerized machine where each remote lock is encrypted with digital code.

With high tech central remote lock like Xenos Great Dane, occupants will feel a sense of security. Theft incidents all over the world are not restricted to night times, but day thefts have become common, with remote locks it is tough for thieves to gain access into the car. With manual locks, there would have been many duplicate keys to have easy access into cars.

To provide an overview of the features of Xenos Great Dane remote or manual central lock. There are operations tucked into a small piece, the lock has a water resistant control unit, water resistant remote, low current consumption, easy installation, vehicle immobilizer, electronic shock sensor adjustment, shock sensor, electronic learn remote, panic mode, disarm or arm chirps, flash light indication, vehicle locate and remote start.

Automobile technology has transformed to new boundaries over the years, the phrase remote locks was not very common even twenty years ago. Car thefts are on the rise, and there are times when thieves enter the car to steal money and expensive ornaments. All these ugly incidences are wiped out with powerful remote locks like Xenos Great Dane central lock. Apart from being a safe and highly advanced software product, Xenos Great Dane central lock is water resistant, and this wipes away the stress factor completely. When a jar of water flown on to the lock, the central lock is still as powerful as when originally brought. It costs Rs 1,097.

Common Light Levels

Common Light Levels Outdoor

Common light levels outdoor at day and night can be found in the table below:
Condition Illumination
(ftcd) (lux)
Sunlight 10,000 107,527
Full Daylight 1,000 10,752
Overcast Day 100 1,075
Very Dark Day 10 107
Twilight 1 10.8
Deep Twilight .1 1.08
Full Moon .01 .108
Quarter Moon .001 .0108
Starlight .0001 .0011
Overcast Night .00001 .0001

Common and Recommended Light Levels Indoor

The outdoor light level is approximately 10,000 lux on a clear day. In the building, in the area closest to windows, the light level may be reduced to approximately 1,000 lux. In the middle area its may be as low as 25 - 50 lux. Additional lighting equipment is often necessary to compensate the low levels.
Earlier it was common with light levels in the range 100 - 300 lux for normal activities. Today the light level is more common in the range 500 - 1000 lux - depending on activity. For precision and detailed works, the light level may even approach 1500 - 2000 lux.
The table below is a guidance for recommended light level in different work spaces:
Activity Illumination
(lux, lumen/m2)
Public areas with dark surroundings 20 - 50
Simple orientation for short visits 50 - 100
Working areas where visual tasks are only occasionally performed 100 - 150
Warehouses, Homes, Theaters, Archives 150
Easy Office Work, Classes 250
Normal Office Work, PC Work, Study Library, Groceries, Show Rooms, Laboratories 500
Supermarkets, Mechanical Workshops, Office Landscapes 750
Normal Drawing Work, Detailed Mechanical Workshops, Operation Theatres 1,000
Detailed Drawing Work, Very Detailed Mechanical Works 1500 - 2000
Performance of visual tasks of low contrast  and very small size for prolonged periods of time 2000 - 5000
Performance of very prolonged and exacting visual tasks  5000 - 10000
Performance of very special visual tasks of extremely low contrast and small size 10000 - 20000

 

Calculating Illumination

Illumination can be calculated as
I = Ll Cu LLF / Al       (1)
where
I = illumination (lux, lumen/m2)
Ll = lumens per lamp (lumen)
Cu = coefficient of utilization
LLF = light loss factor
Al = area per lamp (m2)

Example - Illumination

10 incandencent lamps of 500 W (10600 lumens per lamp) are used in an area of 50 m2. With Cu = 0.6 and LLF = 0.8 illumination can be calculated as
I = 10 (10600 lumens) (0.6) (0.8) / (50 m2)
  = 1018 lux

25 Things I Learned About Life By Age 25



When I turned 25, I wrote down some of the things I've learned over my short time on earth. The last year has been a crazy roller-coaster ride which has enabled me to see certain things like never before.Last year during this time, I was working at what I would consider my "dream job" — well, before I discovered my current "job" (I don't think I can even call it a job).

Over the last year, I've tried to learn from people who have "made it" in life — entrepreneurs, figureheads, lawyers, bankers and even politicians. I've realized that there is no formula to success in life, but there are definitely lessons that can be learned to help along the journey. I came up with the following list which I hope to someday come back to — but for now, I think it's a pretty accurate depiction of how I think. So without further adieu:


1. Take risks when you're young. The older you become, the harder it gets. But they should always be calculated.

2. The most important thing you learn in school is how to learn. Once you master that, nothing will stand in your way. Never stop learning.

How to check AA/AAA alkaline battery using a Multimeter

We all run into a situation when batteries in our remotes, toys, keyboards/mice run out. If we don't know how to check a battery we might throw out a perfectly fine battery (especially when we have a pile of them somewhere in the drawer).

This electronics tip has to deal with checking common alkaline AA/AAA batteries or AA/AAA rechargeable batteries for proper voltage with a voltmeter.

Disclaimer : some people might say that a battery should always be tested under load but I have found that in most common household applications this is insignificant and will not change the results of the testing too much.

Things that you will need :
+ Multimeter/Voltmeter
+ Alkaline battery

Basic facts :
The proper voltage for AA/AAA alkaline battery is 1.5V
The proper voltage for AA/AAA NiCd/NiMh rechargeable battery is 1.25 Volts

Understanding of Railway availiability figures

Understanding availability figures

When you finally get down to booking tickets, you will probably encounter several puzzling availability figures online. After all, finding out that your train and class is "PQWL5/WL5" for the 8th of December isn't very illuminating - what do these figures mean?  Worry not, help is at hand in the form of this tutorial.
There are several different websites you can use to get availability stats for trains, and this tutorial is especially applicable to these four:
  • The official Indianrail website,
  • Erail, 
  • India Rail Info, and
  • IRCTC
Websites like 90di and Cleartrip display availability figures in a slightly different (and simpler) format.  If you plan to stick to only these websites, you might not need this tutorial - you can head straight to the glossary to understand what the terms RAC and waitlist mean.
All screenshots from this tutorial are from Erail, and this tutorial assumes you already know how to read (though not interpret) availability figures displayed on the four sites mentioned earlier.  If not, you can always recap at this link.

[a] Figures like AVAILABLE 75
When seats or berths are available in your train/class, it is fairly simple to understand them.  The AVAILABLE means that seats/berths are available (duh), and the number following the AVAILABLE tells you exactly how many seats/berths are available.  Look at the image below:

Screenshot from www.erail.in
In this case, should I want to travel by First AC (1A) on the 21st of October, I don't have to worry too much as 75 seats are available at the moment.

[b] Figures like RAC87/RAC 74
On trains with sleeping accommodation, after all confirmed berths have been sold out, passengers are usually placed on an RAC ("Reservation Against Cancellation") list.  Being on the RAC list guarantees you a place on the train, with a small catch - you are guaranteed only a seat on the train.  If enough passengers cancel, you will be allotted a sleeping-berth.  
The following image is one for a train-class-date combination that has now reached the RAC list:

Screenshot from www.erail.in
So if I decide to travel by Sleeper Class (SL) on this train on the 8th of November, I will be placed on the RAC list.
Hold on, you might say.  Why are there two sets of numbers?  Why is it RAC87/RAC 74, and what position on the RAC list will you get - 87 or 74?  Good questions. The first number indicates the serial waitlist or RAC position; the second, the running waitlist or RAC position.  I suspect this clears nothing up for you; I'll simplify it a bit more.
The serial number (the first of the two) indicates your position in the queue since the waitlist/RAC list started, and your serial number will never change.  So in this case, all confirmed berths have been sold out, and you are the 87th person to join the queue after the RAC list started.  The second number (the running waitlist/RAC list number) is more important - it denotes the position you currently are at in the waitlist or RAC list.  As and when people cancel their tickets, your running waitlist/RAC list number will reduce until your ticket gets confirmed (if that happens).  So the first number denotes the position you would have been at in the waitlist/RAC list had no cancellations occurred.  So in this case, you would have been RAC87, but as 13 people have cancelled their tickets since the RAC list started, you will be RAC 74 if you book a ticket now.
So why two numbers, you might ask.  Why not just keep the running waitlist number and avoid all confusion?  Well, having two numbers does serve a purpose.  For many passengers who cannot access the net or use technology to find out which coach and berth they've finally been allotted, the only way to check before boarding the train is to look at the charts pasted at the station.  Checking your serial waitlist number on the list is easy - only one person can have a serial RAC position of 87, so all s/he needs to do is look for that entry in the chart.  On the other hand, many people will have the running RAC position of 74 at different times, which makes searching for the entry on the chart significantly more difficult.
Another use of two numbers is that before making your booking, you can:
  • tell how many passengers have already cancelled their tickets,
  • look at cancellation trends for your train and class, which will help you predict its chances of confirmation with greater accuracy.
[c] Figures like GNWL16/WL4
Availability figures like the one seen below for AC Chair Car (CC) on the 1st of October can seem even more perplexing:

Screenshot from www.erail.in
You now (hopefully) recognise the two numbers - the first (16) is the serial position; the second (4), the running position.  But what do GNWL and WL mean?
Four-letter words (not that four-letter word!) when checking availability usually suggest that a waitlist has started.  In trains with sleeping accommodation, the order is usually as follows:
  • If confirmed berths are available, you will be allotted one.
  • Once all confirmed berths have been sold, you will be placed on the RAC list.
  • Once all confirmed berths and RAC positions booked, you will be placed on the waitlist.
Keep in mind that there is no RAC for trains with sitting accommodation (the above screenshot is one such example), and even trains with sleeper accommodation might not have an RAC list depending on the particular quota.  There is no RAC list for First AC Sleeper either.  In all these cases, the availability status moves directly from AVAILABLE to a waitlist.
Back to the example above, the first word tells you that it is a waitlist as well as the type of waitlist.  Here are the types of waitlists you might encounter:
  • GNWL (General Waitlist),
  • CKWL (Tatkal Waitlist),
  • RLWL (Remote Location Waitlist, also abbreviated RLGN),
  • PQWL (Pooled Quota Waitlist),
  • RSWL (Roadside Waitlist)
Different waitlists have different chances of confirmation, so don't ignore this list.  Of all these waitlists, PQWL and RSWL are particularly difficult to get confirmed, with GNWL being the most likely to see confirmations.
Quotas like the foreign tourist quota, the ladies quota, the senior citizen quota, the defence quota and the physically handicapped quota have no waitlists.  Once all confirmed seats or berths have been sold from these quotas, the status changes directly to NOT AVAILABLE.
To wrap up this example, if you book this ticket, you will be 4th on the (general) waitlist.  Expecting four cancellations from other passengers is not too unreasonable in this case, and this ticket will probably get confirmed.

[d] Figures like REGRET/WL300
If I wanted to buy a ticket in Sleeper Class (SL) on this train for the 3rd of November, I wouldn't get very far.

Screenshot from www.erail.in
If you see REGRET as an availability status while trying to book tickets, you're going to have to choose another train or class.  REGRET means that the train-class-date combination is so full that they've stopped issuing tickets even on the waitlist.  In short, the railways know there is no chance that such a high waitlist will get confirmed, so they're telling you to take your business elsewhere.

[e] Figures like GNWL/AVAILABLE
This is a slightly strange figure to see.  The first word suggests a waitlist, so why is there an AVAILABLE after that?
(First AC, 14th October)

Screenshot from www.erail.in
When you see WL/AVAILABLE (irrespective of what type of waitlist it is), it means that at least one seat or berth is available.  This status tells you that the train got full, and hence a waitlist was started, but due to cancellations, seats or berths are now available.  Annoyingly, it doesn't tell you exactly how many seats or berths are available, so the only assumption you can make is that one seat or berth is available.  Only after booking will you know for sure.
If you see WL/AVAILABLE for a train-class combination over a series of dates, it's probably because the railways have decided to add extra coaches of that class to the train - the resulting capacity expansion killing any waitlists.
Alright, that's all folks!
