What is the meaning of life in the Bhagavad Gita?

The ultimate aim is Moksha, (Liberation)

for that there are 4 ways

Karmayoga, bhakthi yoga, Rajayoga and njnana yoga

In my opinion - Karmanye vaadikaraste maaphaleshu kadachana. Do your duties without aspirations for the fruits [for they shall come to you].

Life is a path of existence where we forget the duties that bind us and dwell upon the unnecessary.

The goal of life is to free the mind and intellect from their complexities and to focus them on the glory of the Self by dedicating one's actions to the divine. To seek an abode in the Primordial Universal Consciousness, and to establish one's self in mergence with it, and to became one of its integral parts.

Don't worry about it. All of the answers you need can be found in the Bible.

"do your work but don't expect it's fruit"

bhagavadgita is best

bible is bullsh*t. i read both.
