The mission of life is to revive the dormant divine consciousness in every living being.
The entire process of cosmic arrangement is intended just to give a chance to the conditioned souls to enter the kingdom of God, and there is an adequate arrangement for their maintenance by the nature of the Lord.
Srimad Bhagavatam 3.3.14,
Without being self-controlled, without being disciplined and without being fully obedient, no one can become successful in following the instruction of the spiritual master and without doing so, no one is able to go back to Godhead. — Srimad Bhagavatam, 01.05.24.
When we read Srila Prabhupada’s books, we are sitting in His divine presence, hearing & speaking. When we follow what is in the books we get realizations.
