Yes Rishi. Every day the body self heals and repairs while you sleep. Even walking and day to day activities do put stress on parts of the body. There are small microscopic muscle tears and general wear and tear which is repaired by the body. Million of new cells are formed everyday and old discarded.

Normally a body is made to be disease free but when some some defence mechanism fails or is overwhelmed or when the self repair fails to perform there is manifestation of disease or malady or affliction.

Medicines and Healing Energy serves to kick start that mechanism to self heal. All living things are built this way.
