http://en.wikipedia.org/wiki/Ojas Ojas is a Sanskrit word which literally means "vigor". According to the principles of Ayurveda, it is the essential energy of the body which can be equated with the "fluid of life". Those who practice Ayurveda say that Ojas is the sap of one's life energy which, when sufficient, is equated with immunity and, when deficient, results in weakness, fatigue and ultimately disease.
Ojas (pronounced oh-jus) is the ultimate refined result of digestion, metabolism, absorption and assimilation. The substance that connects the mind to the body and consciousness, it is a wholesome biochemical substance that nourishes all body tissues and has a direct influence on the nature and quality of physical, mental and emotional life. Ojas’ primary location is the heart, from where it circulates to and pervades the entire body. Ojas is collected from the body’s seven tissues — plasma, blood, muscle, adipose tissue (fat), bone, bone marrow, and reproductive tissue (semen and ovum) — by the influence of enzymes (Agnis), similar to how a bee collects honey from the essence of many flowers. The purest substance in the universe and omnipresent in the human being, ojas is responsible for higher states of consciousness, purity of thoughts, perfect health, positivity in feelings, love, joy, better immunity, longevity, intelligence, creativity, memory, bliss, and thought process. When an individual’s inner consciousness awakens spontaneously, ojas increases. In a nutshell, ojas is the sap of the entire physiology and sustains the life of an individual.
