薄伽梵歌 6.14

灵性求道者应拥有心意的宁静，神圣之光唯有在宁静的心意中才能降临。宁静通过根除习气（Vasanas）或欲望和渴求而获得。他应无所畏惧，这是最重要的资格。梵行者（Brahmachari）应全心全意地侍奉上师（Guru），并依靠布施生活，这也构成了梵行誓愿。梵行也意味着节制，精液或生命液能滋养神经和大脑，并激活整个系统。唯有通过梵行誓愿保存此生命力并将其升华为奥贾斯能量（Ojas Shakti）或放射性灵性力量的梵行者，才能长期修习稳定的冥想。

The spiritual aspirant should possess serenity of mind. The Divine Light can descend only in a serene mind. Serenity is attained by the eradication of Vasanas or desires and cravings. He should be fearless. This is the most important alification. A timid man or a coward is very far from Selfrealisation.A Brahmachari (celibate) should serve his Guru or the spiritual preceptor wholeheartedly and should live on alms. This also constitutes the BrahmachariVrata. The aspirant should control the modifications of the mind. He should be balanced in pleasure and pain? heat and cold? honour and dishonour. He should ever think of the Lord and take Him as the Supreme Goal.Brahmacharya also means continence. Semen or the vital fluid tones the nerves and the brain? and energises the whole system. That Brahmachari who has preserved this vital force by the vow,of celibacy and sublimated it into Ojas Sakti or radiant spiritual power can practise steady meditation for a long period. Only he can ascend the ladder of Yoga. Without Brahmacharya or celibacy not an iota or spiritual progress is possible. Continence is the very foundation on which the superstructure of meditation and Samadhi can be built up. Many persons waste this vital energy -- a great spiritual treasure indeed -- when they become blind and lose their power of reason under sexual excitement. Pitiable is their lot They cannot make substantial progress in Yoga.
