Pradyumna: "The Māyāvādīs, who are not in agreement with the existence of the Lord, can be classed in two groups, exemplified by the impersonalist Śaṅkarites of Vārāṇasī and the Buddhists of Saranātha. Both of them are Māyāvādīs, and Kṛṣṇa takes away their knowledge due to their atheistic philosophies. Neither of them agree to accept the existence of a personal God. The Buddhist philosophers clearly deny . . . clearly deny both the soul and God, and although the Śaṅkarites do not openly deny God, they say that the Absolute is nirākāra, or formless. Thus both of them are aviśuddha-buddhayaḥ (SB 10.2.32), or imperfect and unclean in their knowledge and intelligence."
Prabhupāda: What do you think?
Professor: That's . . . of course, in the introduction to Śaṅkara's commentary to Bhagavad-gītā, he does, it seems, if it is for him, which is that . . .
Prabhupāda: He accepts Kṛṣṇa as the Supreme Personality.
Professor: Yes, Kṛṣṇa, yes.
Prabhupāda: Yes.
Professor: So Śaṅkara is a bit difficult, because his followers, even he's Māyāvādī, the followers, his followers, they clearly believe in it. But whether, what Śaṅkara himself meant by it . . .
Prabhupāda: No, that is explained. Śaṅkara is the incarnation of Lord Śiva. He has no fault. He has simply executed the order of the Supreme Lord. But the way in which he has presented the commentary, one should not hear it. That is his warning. Here is the Tenth Canto of Bhāgavatam, two volumes.
Professor: That's also, "Not for sale in India." Why?
Prabhupāda: Because . . .
Professor: Why not in India?
Prabhupāda: India, we make members. We get more price. Because we are, our scheme, Life Member, they pay eleven hundred rupees, and whatever books we can supply, we supply. That's all. That is not even to the amount they pay. So we give our presentation and they contribute. This is the program.
