Śrīmad-Bhāgavatam 2.1.32
Blended reading (Sanskrit + English inline)
The Supreme Lord is not impersonal, as misconceived by less intelligent thinkers. Rather, He is the Supreme Person, as confirmed in all authentic Vedic literatures. But His personality is different from what we can conceive. It is stated here that Brahmājī acts as His genitals and that the Mitrā-varuṇas are His two testicles. This means that as a person He is complete with all bodily organs, but they are of different types with different potencies. When the Lord is described as impersonal, therefore, it should be understood that His personality is not exactly the type of personality found within our imperfect speculation. One can, however, worship the Lord even by seeing the hills and mountains or the ocean and the sky as different parts and parcels of the gigantic body of the Lord, the virāṭ-puruṣa. The virāṭ-rūpa, as exhibited by Lord Kṛṣṇa to Arjuna, is a challenge to the unbelievers.
Dharma is the right side of his chest, because it is said dharmaḥ stanād dakṣiṇataḥ: dharma came from the right side of his chest. (SB 3.12.25) Kaḥ means Brahmā. Medhram means penis. Mitrau refers to Mitrā-varuṇa. Vṛṣanāu means the testicles.
