श्रेयो-धर्मकर्मविचारः
Inquiry into Śreyas, Dharma, and Karma
परं तु शुक्लं विमल॑ विशोक॑ गतकक््लमं सिद्धाति दानवेन्द्र | गत्वा तु योनिप्रभवाणि दैत्य सहस्रश: सिद्धिमुपैति जीव:
paraṁ tu śuklaṁ vimalaṁ viśokaṁ gataklamam siddhāti dānavendra | gatvā tu yoniprabhavāṇi daitya sahasraśaḥ siddhimupaiti jīvaḥ ||
परं तु शुक्लं विमलं विशोकं गतक्लमं सिद्धिदं दानवेन्द्र। गत्वा तु योनिप्रभवानि दैत्य सहस्रशः सिद्धिमुपैति जीवः—मनुष्ययोनिमासाद्य कदाचित्।
भीष्म उवाच
Bhishma teaches that true perfection (siddhi) is associated with a supreme inner condition characterized by purity, stainlessness, freedom from sorrow, and freedom from exhausting agitation; and that the jīva, after innumerable embodied births, may finally attain such perfection—especially upon reaching the human condition where discernment and disciplined practice are possible.
In Shanti Parva’s instruction, Bhishma addresses a Dānava/Daitya interlocutor and explains a doctrinal point: the soul migrates through many womb-born existences, and only after countless births does it sometimes reach a state (and opportunity) conducive to siddhi, described as pure and sorrowless.
