Bhūtasarga-Prakaraṇa
Account of Elemental Creation from Avyakta to Mahat
यस्माद्वृंहयत भावान् ब्रह्मा तेन निरुच्यते / आपूरयति यस्माच्च सर्वान् देहाननुग्रहैः
yasmādvṛṃhayata bhāvān brahmā tena nirucyate / āpūrayati yasmācca sarvān dehānanugrahaiḥ
Because he makes all states of being grow, he is therefore called Brahmā; and because, through his grace, he fills and completes all bodies.
