From the day we took birth and we enter into youth we are guided by the environment to improve our self in any way we can and this has to be done by everyone whether they have greater desire or not. He enhances his body with exercise, knowledge, nutrition and clothing. He started to make his home more fashionable by installing durable objects inside the home. Perfection is the main motto of our life. He tries to improve his abilities and character, fights with the negative traits, adapts to educate him.
He spent most of the time in his life in fulfilling these desires and to excel in the life and as soon as the time passes away and when that time will come when the death is near to us than we start feeling that there is a lot of fear we have inside us regarding the death we are going to face. We worked only on our body to make us strong to face everything in our life but when this tome come than we started facing lot of trouble in our life because we are strong from outer but internally we are not strong enough to face this truth and problems. We are not spiritually awakened that will help us to achieve excellence from inside.
So to face this kind of time in our life than we have to be go for regular meditations and spiritual teachings so that we should be spiritually awakened and enlightened so that we will have no anxiety and fear about the death because Death is the only eternal truth that no one can ignore or move away from it. Death will happen for sure and you should understand it spiritually that soul leaves the body but soul is eternal and will take new form after leaving one body.
This is called as eternity.
