The Universal Form (Virāṭ-Puruṣa): The Lord’s Entry into the Elements, the Devas, and the Origin of Varṇāśrama
हृदयं चास्य निर्भिन्नं चन्द्रमा धिष्ण्यमाविशत् । मनसांशेन येनासौ विक्रियां प्रतिपद्यते ॥ २४ ॥
hṛdayaṁ cāsya nirbhinnaṁ candramā dhiṣṇyam āviśat manasāṁśena yenāsau vikriyāṁ pratipadyate
After that, the heart of the gigantic form separately manifested itself, and into it entered the moon demigod with partial mental activity. Thus the living entity can conduct his mental speculations.
This verse states that when the Universal Person’s heart manifested, Candramā entered it, and by his portion the jīva’s mind becomes active and undergoes changes.
He is explaining cosmic creation: each organ/seat of the Virāṭ-Puruṣa is empowered by a presiding deity, showing that material functions operate under divine governance.
Recognize the mind’s changeable nature and practice steadiness through sādhana (hearing, chanting, remembrance), rather than identifying with every mental fluctuation.
