Ojas

Vital essence; the final refined product of a seven-stage tissue transformation in Ayurvedic physiology. The most refined biological substance the body produces. Stored in the brain. The substrate of sustained intellectual function, spiritual perception, and the prophetess role in its highest female expression.

Ojas (ओजस्) is, in the Ayurvedic physiological system, the final and most refined product of a seven-stage tissue transformation that begins with food.

The chain, from Charaka Samhita, Chikitsasthana:

  1. Anna rasa — chyle (digested food essence)
  2. Rakta — blood
  3. Mamsa — muscle
  4. Meda — fat
  5. Asthi — bone
  6. Majja — bone marrow
  7. Shukra / Artava — reproductive essence (shukra male, rajas female)
  8. Ojas — the refined essence beyond Shukra, produced when the reproductive tissue is conserved rather than expended

Ojas is stored in the brain (the sahasrara / crown region in the chakra system) and is, in the classical description, the substrate of sustained intellectual capacity, spiritual perception, immune resilience, and physical vitality.

Vivekananda's statement

The yogis claim that of all the energies that the human body comprises the highest is what they call Ojas. This Ojas is stored up in the brain, and the more Ojas is in a man's head, the more powerful he is, the more intellectual, the more spiritually strong.

— Swami Vivekananda, Raja Yoga (1896)
