Śrīmad-Bhāgavatam · Text 11.24.19
Who is speaking and story frame
प्रकृतिर्यस्योपादानमाधारः पुरुषः परः ।
सतोऽभिव्यञ्जकः कालो ब्रह्म तत्त्रितयं त्वहम् ॥ १९ ॥
prakṛtir yasyopādānam
ādhāraḥ puruṣaḥ paraḥ
sato ’bhivyañjakaḥ kālo
brahma tat tritayaṁ tv aham
The material universe may be considered real, having nature as its original ingredient and final state. Lord Mahā-Viṣṇu is the resting place of nature, which becomes manifest by the power of time. Thus nature, the almighty Viṣṇu and time are not different from Me, the Supreme Absolute Truth.
