The body is described to have five Koshas – physiological, functioning of body at cellular level. The five Koshas mentioned are:
1) Annamaya – Gross form
2) Pranayama
3) Manomaya Subtle form
4) Vigyanmaya
5) Anandamaya – Casual form
Individual is able to know about various Gross organs of the body, and thus knows Annamaya Kosha. While in Pranayama Kosha, individual is able to be aware of the way in which the energy in various forms is taken into the body however the way in which body uses the energy is not known. Same is the case about Manomaya Kosha; Vigyanmaya Kosha and Anandamaya Kosha. The individual is not aware about functioning of Manomaya, Vigyanmaya and Anandamaya. The individual is thus not aware of three and half Koshas of the body.
