The body has three subtle important elements viz ojas, tejas, and prana. Ojas is believed to be the last essence of semen. It is related to vigor and vitality. Ayurveda gives special importance to these three factors.
Ojas is the super-fine essence of kapha dosha associated with lunar cycles; it is therefore connected to regeneration. The qualities of ojas and kapha dosha are similar: liquid, sweet, and unctuous. Together they provide great support for the immune system and the reserves of life force.
Ojas can be increased by the combination of balanced diet, herbs, proper lifestyle, and yoga.
While building ojas it is also essential to avoid stress and other related factors. One should also focus on cleaning the system with processes like pancha-karma and then rejuvenating the body with rasayana and tonics.
