CHRONOLOGICAL TIME VS PSYCHOLOGICAL TIME
There are two things - chronological time and psychological time. If you are sitting with somebody whom you really love, or who you really care for, you will not notice time pass. Even if you sit for three to four hours together, you will feel that the time flew by. Whereas, if you are sitting with somebody who doesn't interest you, whom you don't really care for, after every five minutes, what will you do? You will check your watch. You will wonder why time is not moving. You will feel so bored.
If the number of thoughts is too much, then the number of kshanas passed will be more and you will feel that too much time has passed whereas only a few minutes might have passed. This is what happens when you are with someone who doesn't interest you. Your mind becomes restless because of that. If the number of thoughts is fewer, the number of kshanas passed will be fewer and you will feel only a little time has passed, whereas a lot of time would have passed by. This is what happens when you are with someone whom you love. That is why we always say that if the number of thoughts is less, you are in heaven. See, for
devatas (heavenly beings), our earthly one year is one day for them! Have you heard this before? Our entire year is one day for them! How is this so? It is because their number of thoughts is so few. So they don't even know how the chronological time moves past so quickly.
That is why in the Chidambaram temple in South Bharat, which is considered to be the temple belonging to the heavenly beings, the presiding deity – Nataraja, will have only six abhishekas (ceremonial baths) in a year. He is worshipped by the devatas. In regular temples, usually we do six pujas per day. But in this particular temple, only six pujas are done in a year itself, because the calendar of the devatas is totally different. The number of thoughts for them is less; they are in heaven. So naturally their kshana, the time between two thoughts is more.
This concept of kshana should be understood clearly. From this we can understand how our one year is only one day for the devatas. The people who are residing in the sixth layer, the spiritual body, are called devatas. That space itself is called heaven.
