Mahārāja Pṛthu's Going Back Home

King Kulaśekhara wanted to give up his body while in a healthy state, and he thus prayed to Kṛṣṇa to let him die immediately while he was in good health and while his mind was sound. When a man dies, he is generally overpowered by mucus and bile, and thus he chokes. Since it is very difficult to vibrate any sound while choking, it is simply by Kṛṣṇa's grace that one can chant Hare Kṛṣṇa at the time of death. However, by situating oneself in the  muktāsana  position, a  yogī  can immediately give up his body and go to whatever planet he desires. A perfect  yogī  can give up his body whenever he desires through the practice of  yoga .
