Dhritarashtra said The true knowledge, that you are speaking of attainable by hard asceticism, is unborn in the mind and needs not any efforts for its manifestation and is manifested during the seeking of Brahma. How then can that immortality which is connected with a knowledge of the Supreme soul be obtained?
धृतराष्ट्र उवाच यत् सनातनी अत्यन्तविद्यामिति ब्रवीषि त्वं ब्रह्मचर्येण सिद्धाम्। अनारभ्यां वसतीह कार्यकाले कथं ब्राह्मण्यममृतत्वं लभेत॥
