Oja (ओजा, IAST: ojā) is an Sanskrit-origin Hindu girl-name meaning “Vital strength; inner radiance”. From ojas — the subtle vital essence in Ayurveda; the radiance of true health.

Meaning, etymology & significance

Oja (ओजा) — feminine of ojas — names one of the most important concepts in Ayurveda: the subtle vital essence that is the substance of immunity, of glow, of the lustre of well-being. Charaka calls ojas the “sap of all the dhātus” (tissues), the eighth and most refined product of digestion.

In the Upanishads ojas is associated with the radiant strength of the inner spirit. The Vedas describe ojas as the very vigour of Indra — the king of devas — and the gift of Soma, the lunar elixir.
