The Subtle Body - An understanding

Disciple: What is the composition of the subtle body?
Guru: The subtle body is composed of nineteen principles (Tattvas), viz., five Jnana Indriyas or organs of knowledge, five Karma Indriyas or organs of action, five Pranas or vital airs, Manas or mind, Buddhi or intellect, Chitta or the subconscious and Ahamkara or the ego. It is a means of enjoying pleasure and pain.

Disciple: When will this subtle body get dissolved?
Guru: It gets dissolved in Videha Mukti or disembodied Liberation.
