Brahmacharya (Celibacy); "A state of the individual where the life-force (prana) is always found directed upwards". MMY/Gita Appendix
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. (Wiki) Samson was a Herculean hero undone by Delila (whom he has sex with) who discovered the secret of his great strength (which was his Ojas brought about through Celibacy) represented by his long hair, (my interpretation). A moral lesson of the Bible.
