Prabhupāda: Yes. What is that universal form? It is nothing. Any powerful living being can do that.
Yaśodānandana: In the other Vaiṣṇava-sampradāyas, such as the Madhva-sampradāya and the Rāmānuja-sampradāya, they do not understand that Kṛṣṇa has His own planet, Goloka Vṛndāvana. They think that there is only Vaikuṇṭha and nothing else.
Prabhupāda: Their knowledge is imperfect. In the Brahma-saṁhitā it is said, goloka-nāmni nija-dhāmni tale ca tasya (Bs. 5.43).
