"After reading... Bhagavad-gita is the summary of Vedic literature. You cannot read all the Vedas at the present moment, neither you have time, nor you have got the capacity. In this Kali-yuga, mandah sumanda-matayo [SB 1.1.10], everyone is fallen. Manda-bhagya. So this human life should be utilized for understanding the Vedic knowledge, divya-jnana then he'll be purified, tapo divyam yena suddhyed sattvam [SB 5.5.1]. My existential identity will be purified. At the present moment it is not purified. Because it is not purified, therefore we are repeatedly dying. But there is no knowledge how to stop death. They think death is natural. It is not natural. It is unnatural. They do not know it. But in the Bhagavad-gita you'll get the information, na jayate na mriyate va kadacin: 'The soul is never born, never dies.' Na jayate na mriyate va kadacin. 'I see he's died, he is dead.' No, he's not dying, his body is being annihi... Na hanyate hanyamane sarire [Bg. 2.20]. By seeing the body is destroyed don't think he's destroyed. He'll get another body. Tatha dehantara-praptir dhiras tatra na muhyati [Bg. 2.13]. So this is our position. We have accepted one body, and we live in that body for some days, and then again we give up this body, tatha dehantara-praptir. So this is disease. So in order to get out of this disease there is necessity of tapasya, how to stop this disease."
