Srimad Bhagavatham : 6.1.31.
Slokam-31. ( The order carriers of Yamaraja ( Lord of death ) were snatching the soul from the core of the heart of Ajamila, the husband of the prostitute, but with resounding voices the messengers of Lord Vishnu, the Vishnudutas, forbade them to do so. )
vikarsatontar hrdayad dasi-patim ajamilam
yama-presyan vishnuduta varayam-asur-ojasa.
vikarsatah = snatching;
antah hrdayat = from within the heart;
dasi-patim = the husband of the prostitute;
ajamilam = Ajamila;
yama-presyan = the messengers of Yamaraja ( Lord of death );
vishnu-dutah = the order carriers of Lord Vishnu;
varayam asuh = forbade;
ojasa = with resounding voices.
A Vaishnava, one who has surrendered to the lotus feet of Lord Vishnu, is always protected by Lord Vishnu’s order carriers. Because Ajamila had chanted the holy name of Narayaṇa, the Vishnudutas not only immediately arrived on the spot but also at once ordered the Yamadutas not to touch him. By speaking with resounding voices, the Vishnudutas threatened to punish the Yamadutas if they continued trying to snatch Ajamila’s soul from his heart. The order carriers of Yamaraja have jurisdiction over all sinful living entities, but the messengers of Lord Vishnu, the Vishnudutas, are capable of punishing anyone, including Yamaraja, if he wrongs a Vaishnava.
Materialistic scientists do not know where to find the soul within the body with their material instruments, but this slokam clearly explains that the soul is within the core of the heart (hrdaya); it is from the heart that the Yamadutas were extracting the soul of Ajamila.
Similarly, we learn that the Supersoul, Lord Vishnu, is also situated within the heart
( isvaraa sarva-bhutanam hrddeserjuna tishthati [Bg. 18.61]).
In the Upaniṣads it is said that the Supersoul and the individual soul are living in the same tree of the body as two friendly birds. The Supersoul is said to be friendly because the Supreme Personality of Godhead is so kind to the original soul that when the original soul transmigrates from one body to another, the Lord goes with him. Furthermore, according to the desire and karma of the individual soul, the Lord, through the agency of maya, creates another body for him.
The heart of the body is a mechanical arrangement. As the Lord says in Bhagavad-gītā (18.61):
isvarah sarva-bhutanam hrddeserjuna tishthati
bhramayan sarva-bhutani yantrarudhani mayaya.
“The Supreme Lord is situated in everyone’s 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. One’s body is created through the agency of maya (karmana daiva-netrena), and according to one’s activities in this life, another vehicle is created, again under the supervision of daivi maya (daivi hyesa guna-mayi mama maya duratyaya ). At the appropriate time, one’s 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.
