Formed by modification of the food consumed. This is the only Gross Sheath that is visible which is nothing but the Gross Body. Food consumed by the parents being the source (anna rasa) of the child. The body at the end which goes back to earth which is the source of the food.
Pranamaya Kosha – Energy Sheath
Consisting of Pranic Energy. This is the Karmendriyas & Gnanendriyas of Sukshma Sareera. Food consumed is converted into the Energy (Pancha Pranas) and used as Kriya Shakti for the actions with Karmendriyas.
Manomaya Kosha – Mental Sheath
Representing the Physcological/ Emotional layer of the personality. This is the mind component of Sukshma Sareera. This represent the Icha Shakthi which generates the desires to be fulfilled by the Pranamaya Kosha using the Annamaya Kosha.
Vigyanamaya Kosha – Intellectual Sheath

Aanadamaya Kosha – Bliss Sheath
