The living entity is covered by two different types of bodies — the gross body and the subtle body. At death we can see that the gross body is finished, but actually the living entity is carried by the subtle body to another gross body. The so-called scientists of the modern age cannot see how the subtle body is working in carrying the soul from one body to another. This subtle body has been figuratively described as a serpent, or the city’s police superintendent. When there is fire everywhere, the police superintendent cannot escape either. When there is security and an absence of fire in the city, the police superintendent can impose his authority upon the citizens, but when there is an all-out attack on the city, he is rendered useless. As the life air was ready to leave the gross body, the subtle body also began to experience pain.
