द्रव्यसूक्ष्मविपाकश्च धूमो रात्रिरपक्षय: । अयनं दक्षिणं सोमो दर्श ओषधिवीरुध: ॥ ५० ॥ अन्नं रेत इति क्ष्मेश पितृयानं पुनर्भव: । एकैकश्येनानुपूर्वं भूत्वा भूत्वेह जायते ॥ ५१ ॥
dravya-sūkṣma-vipākaś ca dhūmo rātrir apakṣayaḥ ayanaṁ dakṣiṇaṁ somo darśa oṣadhi-vīrudhaḥ
My dear King Yudhiṣṭhira, when oblations of ghee and food grains like barley and sesame are offered in sacrifice, they turn into celestial smoke, which carries one to successively higher planetary systems like the kingdoms of Dhumā, Rātri, Kṛṣṇapakṣa, Dakṣiṇam and ultimately the moon. Then, however, the performers of sacrifice descend again to earth to become herbs, creepers, vegetables and food grains. These are eaten by different living entities and turned to semen, which is injected into female bodies. Thus one takes birth again and again.
This is explained in Bhagavad-gītā (9.21) :
This verse outlines the Pitṛyāna sequence after death—smoke, night, the dark fortnight, the sun’s southern course, the moon, the new-moon day—leading to rebirth through vegetation and food.
Parīkṣit was preparing for death and liberation; Śukadeva taught him how karmic routes bind the soul to repeated birth, contrasting them with the liberating path of devotion.
It encourages detachment from karma-based goals and motivates steady bhakti—hearing and chanting—so one does not return to repeated rebirth.
