What is Meditation?
Meditation is changing human mind to universe mind and thus is being reborn as the body and mind of the universe. If you are reborn as the Universe you will eternally never die.
Is there anything in the world that is as important as living forever?
The human mind is a picture that man has taken of the world, and his self lives inside that picture. Therefore, if you get rid of that world of pictures, you become the Universe Mind. It is necessary to be born as the Truth which is the body and mind of the universe in order to live eternally.
