薄伽梵歌 6.14

靈性修行者應當擁有心靈的寧靜。神聖之光只能降臨於寧靜的心靈。寧靜是透過根除習氣（Vasanas）、慾望和渴求而獲得的。他應當無所畏懼，這是最重要的資格。一個膽怯或懦弱的人，離「真我」實證（Self-realisation）甚遠。「獨身戒」（Brahmacharya）也意味著貞潔。精液或生命液能滋養神經和大腦，並為整個系統注入能量。那些透過貞潔誓願保存了這種生命力，並將其昇華為「奧賈斯沙克蒂」（Ojas Sakti）或光輝靈性力量的「獨身者」（Brahmachari），才能長期修習穩定的冥想。唯有他才能攀登「瑜伽」（Yoga）的階梯。

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.
