Bhagavad Gita 8.11

यदक्षरं वेदविदो वदन्तिविशन्ति यद्यतयो वीतरागाः।यदिच्छन्तो ब्रह्मचर्यं चरन्तितत्ते पदं संग्रहेण प्रवक्ष्ये ॥८.११॥

yadakṣaraṃ vedavido vadantiviśanti yadyatayo vītarāgāḥyadicchanto brahmacaryaṃ carantitatte padaṃ saṃgraheṇa pravakṣye

That which is declared to be Imperishable by those who know the Vedas, that which the self-controlled (ascetics or Sannyasins) and passion-free enter, that goal, desiring which celibacy is practised, I will declare to thee in brief.
