The intuition that Śrīla Prabhupāda’s words are perfect, without defect, even when not explicitly backed by śāstra is definitely the correct understanding. When a devotee is perfect in Kṛṣṇa consciousness, like Śrīla Prabhupāda, he not only perfectly sees Kṛṣṇa, but also perfectly sees Kṛṣṇa’s material energies as well. A pure devotee has none of the four defects of conditioned souls. Kṛṣṇadāsa Kavirāja Gosvāmī says: bhrama, pramāda, vipralipsā, karaṇāpāṭava, ārṣa-vijña-vākye nāhi doṣa ei saba, “Mistakes, illusions, cheating and defective perception do not occur in the sayings of the authoritative sages.”
