CC Madhya 6.143
sei brahme punarapi haye yāya laya
In the Taittirīya Upaniṣad (3.1) it is said, yato vā imāni bhūtāni jāyante: “The entire material cosmic manifestation is born of the Supreme Brahman.” Also, the Brahma-sūtra begins with the verse janmādy asya yataḥ: “The Absolute Truth is that from whom everything emanates.” (Bs. 1.1.2) That Absolute Truth is Kṛṣṇa. In the Bhagavad-gītā (10.8), Kṛṣṇa says, ahaṁ sarvasya prabhavo mattaḥ sarvaṁ pravartate: “I am the source of all spiritual and material worlds. Everything emanates from Me.” Therefore Kṛṣṇa is the original Absolute Truth, the Supreme Personality of Godhead. Again, Kṛṣṇa states in the Bhagavad-gītā (9.4), mayā tatam idaṁ sarvaṁ jagad avyakta-mūrtinā: “By Me, in My unmanifested form, this entire universe is pervaded.” And as confirmed in the Brahma-saṁhitā (5.37), goloka eva nivasaty akhilātma-bhūtaḥ: “Although the Lord always stays in His abode, Goloka Vṛndāvana, He is still all-pervading.” His all-pervasive feature is understood to be impersonal because one does not find the form of the Lord in that all-pervasiveness. Actually, everything is resting on the rays of His bodily effulgence. The Brahma-saṁhitā (5.40) also states:
yasya prabhā prabhavato jagad-aṇḍa-koṭi-
Due to the rays of the Lord’s bodily effulgence, millions of universes are created, just as planets are created from the sun.
