Ātma-saṃyama-dharma: One-pointedness of Mind and Senses (शुक–व्यास संवादः)
ब्रह्मचर्येण वै लोकान् जयन्ति परमर्षय: । आत्मनश्व ततः श्रेयांस्यन्विच्छन् मनसा55त्मनि
brahmacaryeṇa vai lokān jayanti paramarṣayaḥ | ātmanaś ca tataḥ śreyāṃsy anvicchan manasā ātmani ||
ब्रह्मचर्येण वै लोकान् जयन्ति परमर्षयः । आत्मनश्च ततः श्रेयांस्यन्विच्छन् मनसा आत्मनि ॥
व्यास उवाच
Brahmacarya—understood as rigorous restraint and purity of conduct—gives sages mastery over worldly and spiritual attainments; but its higher purpose is inward: turning the mind within to seek the supreme good (śreyas) through self-inquiry centered on the ātman.
In the didactic flow of the Śānti Parva, Vyāsa is presenting an ascetic-ethical principle: the great sages, through disciplined brahmacarya, gain ‘victory over the worlds’ and then proceed to the deeper quest—seeking ultimate welfare by directing the mind inward toward the Self.
