The Krsna consciousness movement, therefore, offers a process of transcendental activities wherein the mind is fully absorbed in affairs pertaining to Krsna. The presence of the soul is perceived by consciousness, and one must purify his consciousness from material to spiritual, or, in other words, to Krsna consciousness. That which is spiritual is eternal, and that which is material is temporary. Without Krsna consciousness, ones consciousness is always absorbed in temporary things. For everyone, therefore, Krsna recommends in Bhagavad-gita (9.34), man-mana bhava mad-bhakto mad-yaji mam namaskuru. One should always be absorbed in thought of Krsna, one should become His devotee, one should always engage in His service and worship Him as the supreme great, and one should always offer Him obeisances. In the material world one is always a servant of a greater person, and in the spiritual world our constitutional position is to serve the Supreme, the greatest, param brahma. This is the instruction of Sri Caitanya Mahaprabhu. Jivera svarupa hayakrsnera nitya-dasa (Cc. Madhya 20.108).

To act in Krsna consciousness is the perfection of life and the highest perfection of yoga. As Lord Krsna says in Bhagavad-gita (6.47):

The condition of the mind, which flickers between sankalpa and vikalpa, accepting something and rejecting it, is very important in transferring the soul to another material body at the time of death.

Because the mind is ultimately controlled by the Supreme Personality of Godhead, Krsna, the word apasmrtih is significant. Forgetfulness of ones own identity is called apasmrtih. This apasmrtih can be controlled by the Supreme Lord, for the Lord says, mattah smrtir jnanam apohanam ca: [Bg. 15.15] From Me come remembrance, knowledge and forgetfulness. Instead of allowing one to forget ones real position, Krsna can revive ones original identity at the time of ones death, even though the mind may be flickering. Although the mind may work imperfectly at the time of death, Krsna gives a devotee shelter at His lotus feet. Therefore when a devotee gives up his body, the mind does not take him to another material body (tyaktva deham punar janma naiti mam eti [Bg. 4.9]); rather, Krsna takes the devotee to that place where He is engaged in His pastimes (mam eti), as we have already discussed in previous verses. Ones consciousness, therefore, must always be absorbed in Krsna, and then ones life will be successful. Otherwise the mind will carry the soul to another material body. The soul will be placed in the semen of a father and discharged into the womb of a mother. The semen and ovum create a particular type of body according to the form of the father and mother, and when the body is mature, the soul emerges in that body and begins a new life. This is the process of transmigration of the soul from one body to another (tatha dehantara-praptih). Unfortunately, those who are less intelligent think that when the body disappears, everything is finished. The entire world is being misled by such fools and rascals. But as stated in Bhagavad-gita (2.20), na hanyate hanyamane sarire. The soul does not die when the body is destroyed. Rather, the soul takes on another body.
