उशनसः (शुक्रस्य) चरितम् — The Account of Uśanā (Śukra): Yoga, Grievance, and Pacification
तथा कर्मफलैदेंही र|ज्जितस्तमसा55वृत: । विवर्णों वर्णमश्रित्य देहेषु परिवर्तते
tathā karmaphalaiḥ dehī rañjitas tamasāvṛtaḥ | vivarṇo varṇam āśritya deheṣu parivartate ||
بھیشم نے کہا—اسی طرح دہہ دار آتما کرم کے پھلوں سے رنجیدہ اور تَمَس (جہالت) سے ڈھکی ہوئی، خود بے رنگ ہوتے ہوئے بھی کسی ایک حالت کا سہارا لے کر “رنگ” اختیار کرتی ہے اور اجسام میں بار بار گردش و تبدیلی کرتی رہتی ہے۔
भीष्म उवाच
The self is intrinsically unqualified ("colorless"), but ignorance (tamas) veils it and karma’s results stain it, making it appear to take on particular qualities and roles; this drives its repeated movement through different bodies (saṃsāra).
Bhishma is instructing on the metaphysics of rebirth: he uses an analogy of wind darkened by contact with colored powders to explain how the jīva, though pure in itself, seems to acquire attributes through ignorance and karmic conditioning and thus cycles through embodiments.
