Brahmacharya -Sri Sankaracharya.

1. Brahmacharya or spotless chastity is the best of all penances; a celibate of such spotless chastity is not a human being, but a god indeed… To the celibate who practises unbroken brahmacharya, what is there unattainable in this world? By the power of the unbroken brahmacharya, one will become just like myself.
2. In his celebrated work “Vivekachudamani,” Sri Sankaracharya, one of the brightest stars in the philosophical and religious firmament of India, has this advice for spiritual aspirants: “If, indeed, thou hast a craving for liberation, shun sense-objects from a good distance as thou wouldst do poison, and always cultivate carefully the nectar-like virtues of contentment, compassion, forgiveness, straight-forwardness, calmness and self-control.”
