In the material body, which is called the "sheath of food" (anna-maya kosha), reign the elements earth, water, and fire, which are those presiding in the lowest Chakra, the Muladhara, Svadhishthana, and mani-pura centres. The two former produce food and drink, which is assimilated by the fire of digestion, and converted into the body of food. The indriya are both the faculty and organs of sense. There are in this body the material organs, as distinguished from the faculty of sense.

In the gross body (sharira-kosha) there are six external kosha – viz., hair, blood, flesh, which come from the mother, and bone, muscle, marrow, from the father.

The organs of sense (indriya) are of two kinds – viz.: jnanendriya, or organs of sensation, through which knowledge of the external world is obtained (ear, skin, eyes, tongue, nose); and karmendriya, or organs of action – mouth, arms, legs, anus, penis, the functions of which are speech, holding, walking, excretion, and procreation.
