able to give up all other methods of self-realization. In other words, when one firmly realizes Kṛṣṇa as the supreme goal, he is no longer attracted by mystic yoga practice or the speculative empirical methods of knowledge.

In  Bhagavad-gītā  it is also confirmed:  yam yam vāpi smaran bhāvam tyajaty ante kalevaram/ tam tam evaiti kaunteya sadā tad-bhāva-bhāvitaḥ  (Bg. 8.6). Those who are practicing Kṛṣṇa consciousness know that their examination will be held at the time of death. If one can remember Kṛṣṇa at death, he is immediately transferred to Goloka Vṛndāvana, or Kṛṣṇaloka, and thus his life becomes successful. Pṛthu Mahārāja, by the grace of Kṛṣṇa, could understand that the end of his life was near, and thus he became very jubilant and proceeded to completely give up his body on the  brahma-bhūta  stage by practicing the yogic process. It is thoroughly described in the following verses how one can voluntarily give up this body and return home, back to Godhead. The yogic process practiced by Pṛthu Mahārāja at the time of death accelerates the giving up of this body while one is in sound health physically and mentally. Every devotee desires to give up the body while it is sound physically and mentally. This desire was also expressed by King Kulaśekhara in his  Mukunda-mālā-stotra :
