The body is sustained on four things

4-61 Muhammad ibn Musa ibn al-Mutawakkil رضي الله عنه narrated that Muhammad ibn Yahya al-Attar quoted Muhammad ibn Ahmad, on the authority of Durost, on the authority of Abil Asbaq that Aba Abdillah عليه السلام said, “The body is based on four things: the spirit, the mind; the blood and the self. Once the spirit departs the body, the mind shall follow it. Once the spirit sees something, it will be saved by the mind and maintained by the blood and the self.”
