The Supreme Lord is situated in everyones heart, O Arjuna, and is directing the wanderings of all living entities, who are seated as on a machine, made of the material energy. Yantra means a machine, such as an automobile. The driver of the machine of the body is the individual soul, who is also its director or proprietor, but the supreme proprietor is the Supreme Personality of Godhead. Ones body is created through the agency of maya (karmana daiva-netrena), and according to ones activities in this life, another vehicle is created, again under the supervision of daivi maya (daivi hy esa guna-mayi mama maya duratyaya). At the appropriate time, ones next body is immediately chosen, and both the individual soul and the Supersoul transfer to that particular bodily machine. This is the process of transmigration. During transmigration from one body to the next, the soul is taken away by the order carriers of Yamaraja and put into a particular type of hellish life (naraka) in order to become accustomed to the condition in which he will live in his next body.
