brahmcharya.

Brahmacharya is a mode of life that is always beneficial, immaterial of the duration. The benefits and positive results increase with longer duration and intensity when carried out rightly. Twelve years of unbroken Brahmacharya lead to benefits of a superior nature and bestow many siddhis to the practitioner along with proximity to self-realization.
