Saṃhāra-krama (The Sequence of Cosmic Dissolution) — Yājñavalkya’s Discourse
युक्तस्तथायमात्मानं योग: पार्थिव निश्चलम् । करोत्यमलमात्मानं भास्करोपमदर्शनम्,पृथ्वीनाथ! जैसे सिरपर रखे हुए तेलसे भरे पात्रकी ओर मनको स्थिरभावसे लगाये रखनेवाला पुरुष एकाग्रचित्त हो सीढ़ियोंपर चढ़ जाता है और जरा भी तेल नहीं छलकता, उसी तरह योगी भी योगयुक्त होकर जब आत्माको परमात्मामें स्थिर करता है, उस समय उसका आत्मा अत्यन्त निर्मल तथा अचल सूर्यके समान तेजस्वी हो जाता है
bhīṣma uvāca | yuktas tathāyam ātmānaṃ yogaḥ pārthiva niścalam | karoty amalam ātmānaṃ bhāskaropama-darśanam ||
Bhishma said: “O king, when this Yoga is properly practiced, it makes the self steady and unmoving. It purifies the inner being, and the yogin’s awareness becomes radiant—like the sun—clear in vision and free from stain.”
भीष्म उवाच
Yoga, when practiced with discipline, steadies the mind/self and purifies it; from that purity arises luminous clarity of perception, compared to the radiance of the sun.
In the Shanti Parva’s instruction section, Bhishma continues advising the king on inner discipline: he explains the effect of yoga practice—stability, purity, and radiant insight—using the sun as a metaphor for the yogin’s clarified awareness.
