The Supreme Personality of Godhead, Kṛṣṇa, is the original cause, as confirmed in Bhagavad-gītā (ahaṁ sarvasya prabhavaḥ (BG 10.8)). Even this material world, which is conducted under the modes of material nature, is caused by the Supreme Personality of Godhead, who therefore also has an intimate relationship with the material world. If the material world were not a part of His body, the Supreme Lord, the supreme cause, would be incomplete. Therefore we hear, vāsudevaḥ sarvam iti sa mahātmā sudurlabhaḥ: (BG 7.19) if one knows that Vāsudeva is the original cause of all causes, he becomes a perfect mahātmā.
The Brahma-saṁhitā (BS 5.38) declares:
- īśvaraḥ paramaḥ kṛṣṇaḥ
- sac-cid-ānanda-vigrahaḥ
- anādir ādir govindaḥ
- sarva-kāraṇa-kāraṇam
"Kṛṣṇa, who is known as Govinda, is the supreme controller. He has an eternal, blissful, spiritual body. He is the origin of all. He has no other origin, for He is the prime cause of all causes." The Supreme Brahman (tad brahma) is the cause of all causes, but He has no cause. Anādir ādir govindaḥ sarva-kāraṇa-kāraṇam: (BS 5.1) Govinda, Kṛṣṇa, is the original cause of all causes, but He has no cause for His appearance as Govinda. Govinda expands in multifarious forms, but nevertheless they are one. As confirmed by Madhvācārya, ananyaḥ sadṛśābhāvād eko rūpādy-abhedataḥ: Kṛṣṇa has no cause nor any equal, and He is one because His various forms, as svāṁśa and vibhinnāṁśa, are nondifferent from Himself.
