It is recommended to understand Cosmic year in order to understand better in the context of Cosmic year.
As a human being, the most important thing is its life. Without its life, nothing can be more important. Anything that we can think of in our daily life such as money, fame, power, etc. can not be more important because once my life is gone, everything is useless. How one can be rich, famous, and influential without having himself/herself?
