CC Madhya 6.143
sei brahme punarapi haye yāya laya
“Everything in the cosmic manifestation emanates from the Absolute Truth, remains in the Absolute Truth, and after annihilation again enters the Absolute Truth.
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:
Due to the rays of the Lord’s bodily effulgence, millions of universes are created, just as planets are created from the sun.
