The Vaiśeṣika school of Indian philosophy analyzes reality through categories and substances. The relationship between the self (ātman) and the body is a key topic.
Vaiśeṣika identifies specific types of relations:
In Vaiśeṣika, the self (ātman) is considered a distinct, eternal substance, separate from the physical body. The body is also a substance, but it is perishable.
The connection enabling the self to experience the physical world through the body is best described by Saṃyoga. This relation signifies an association between the distinct substances (self and body) which allows for interaction and experience, but it is not an essential, inherent connection like Samavāya.
Therefore, the Vaiśeṣikas relate the self to the body by the relation of Saṃyoga.
