Oja is the cumulative essence remaining after the cycle of dhatu nutrition is complete. Our physical, mental, and spiritual strength is totally dependent on oja. Our personal aura, the strength and glow we are meant to exude, is produced from an abundance of oja. This is our best safeguard against mental and physical disease. As oja thrives, so does the body’s natural immunity. Mental clarity and cognitive memories flourish. If, on the other hand, the body has insufficient rasa, the tissues become dry and contaminated, resulting in the depletion of oja. Decreased oja also fosters an increase in the ama, or wastes, produced by the body thus hampering the physical and mental capacity of an individual.
Thus,Oja is considered as essence, produced after the formation of the seven types of dhatus which are responsible for vitality in the body & for leading energy to make a person physically active. It is of 2 types:
1. para-oja: present in the heart in 8 bindu parinama
2. apara oja: present in the whole body in ½ anjuli parinama
