Śānti-parva 206: Guṇa-hetu Moha, Kāma-krodha Chain, Indriya-utpatti, and Nirodha
अव्यक्तात्मा पुरुषो व्यक्तकर्मा सोव्यक्तत्वं गच्छति हुन्तकाले । तैरेवायं चेन्द्रियैर्वर्थमानै- ग्लयद्िवा5वर्ततेडकामरूप:,पुरुषका आत्मा (वास्तविक स्वरूप) अव्यक्त है और उसके कर्म शरीररूपमें व्यक्त हैं। अतः वह अन्तकालमें अव्यक्तभावको प्राप्त हो जाता है। परंतु कामनाओंसे तद्गरूप हुआ वह जीव उन बढ़ी हुई विषयप्रबल इन्द्रियोंसे युक्त होकर पुनः संसारमें आ जाता है अर्थात् पुनः शरीरको धारण कर लेता है

Bhishma said: The person’s true self is unmanifest (avyakta), while his actions are manifest through the body. Therefore, at the time of death he passes into the unmanifest state. Yet, shaped by desire, the embodied being—carrying those very senses that have grown powerful through their objects—returns again to worldly existence, taking up another body.
भीष्म उवाच
The self is subtle and unmanifest, but actions and sense-engagement are manifest; at death one enters an unmanifest condition, yet if desire persists and the senses remain strengthened by objects, the being returns to saṁsāra and takes another body.
In the Śānti Parva’s instruction on dharma and liberation, Bhīṣma explains to the listener (Yudhiṣṭhira in this parva) how the momentum of desire and sense-habits drives continued rebirth even after the dissolution of the body at death.
