सांख्ययोगभेदः तथा योगबलोपदेशः
Sāṃkhya–Yoga Distinction and Instruction on Yogic Strength
तत्संयोगेन बुद्धि चाप्पपश्यत् स तु शंकर: । महामतिरचिन्त्यात्मा सत्यधर्मरत: सदा,तत्पश्चात् परम् बुद्धिमान, अचिन्त्यस्वरूप और सदा सत्यधर्मपरायण महादेवजीने अपनी तपस्याके सम्पर्कसे उशनाकी तपस्यामें भी वृद्धि हुई देखी
tat-saṃyogena buddhiṃ cāpaśyat sa tu śaṅkaraḥ | mahā-matir acintyātmā satya-dharma-rataḥ sadā ||
ビーシュマは言った。「その交わりによって、シャンカラは知性のはたらきを見て取った。大いなる心を持ち、内なる本性は不可思議にして、常に真実とダルマに帰依するマハーデーヴァは、己がタパスの触れ合いによって、ウシャナーのタパスさえも増大したことを悟ったのである。」
भीष्म उवाच
A being firmly established in satya and dharma elevates others through contact; true spiritual power is not competitive but augmentative—tapas can increase in another when guided or touched by a higher, dharmic presence.
Bhishma describes Śaṅkara observing, through their association, the functioning of buddhi and noticing that his own ascetic potency, when brought into contact, caused an increase in Uśanā’s austerity as well.
