In Yogic and Ayurvedic philosophy, the Annamaya Kosha (literally "the sheath made of food") refers to your physical body—the bones, muscles, skin, and organs. It is the most tangible of the five layers of existence (Panchakoshas). Therapy for this kosha focuses on the "gross" or material level to ensure the physical "vessel" is strong enough to support deeper mental and spiritual work.
