Just like Caitanya Mahāprabhu embraced the brāhmaṇa who was illiterate, but he took the essence of Bhagavad-gītā, the relationship between the Lord and the devotee. Therefore, unless we take the real, I mean to say, essence of any literature, it is simply waste of time.
- tāṅhāra nāhika doṣa, īśvara-ājñā pāñā
- gauṇārtha karila mukhya artha ācchādiyā
- (CC Adi 7.110)
Now, at the beginning, He criticized Śaṅkarācārya that "If somebody hears Śaṅkarācārya's commentation, then he's sure to be doomed." But again He supports Śaṅkarācārya. Why? Śaṅkarācārya is the incarnation of Lord Śiva, and he's a great devotee. Śaṅkara... Vaiṣṇavānāṁ yathā śambhuḥ: "There are many devotees of the Lord, but the foremost devotee is Lord Śiva." And he has got a disciplic succession which is called Viṣṇu Svāmī-sampradāya. So Śaṅkarācārya was covered devotee. He's covered devotee. His aim was to bring men to the standard of devotional service, but the time and circumstances in which he was preaching, he could not place his real object because they were unable to understand. At last, at the end of his life, he composed so many poetries in praise of Vṛndāvana-līlā, and especially his very famous Catpar pandika (?), that is, he has stated,
- bhaja govindaṁ bhaja govindaṁ
- bhaja govindaṁ mūḍha-mate
- prāpte sannihite kāla maraṇe
- na hi na hi rakṣati ḍukṛñ-karaṇe
"My dear foolish brothers, you kindly worship Kṛṣṇa, Govinda..." Thrice he has said, bhaja govindaṁ bhaja govindaṁ bhaja govindaṁ mūḍha-mate. Mūḍha-mate means "You foolish nonsense, you kindly worship Govinda." Why? Now, prāpte sannihite kāla maraṇe: "When death will be nearer, your this grammatical interpretation, ḍukṛñ karaṇe, this pratha (?), that pratha (?), arguing, jugglery of words, will not save you, will not save you. You please worship Govinda." That is his instruction. And there are many others.
So Śaṅkarācārya was a covered devotee. He was devotee. Somebody accuses Śaṅkarācārya that he was covered Buddhist. But so far I am concerned, I say that Śaṅkarācārya was covered devotee. He was devotee at heart, but because he was ordered to preach in that way... Otherwise, there was no alternative. That is stated in the Padma Purāṇa. When there is conversation between Lord Śiva and his wife Pārvatī, he disclosed that "In the age of Kali, as a Brāhmaṇa, I preach this Māyāvāda philosophy, which is covered Buddha philosophy." Buddha philosophy says that "This material life is all. After this material life, there is nothing, all void." And Śaṅkarācārya said that "It is impersonal. There is no variety." So in both the philosophies there is no acceptance of Lord, the Supreme Lord, Personality of Godhead. Therefore they are called nāstika-vāda. Nāstika-vāda means atheism, atheism. Caitanya Mahāprabhu has described Buddha religion as atheism. "And Māyāvāda philosophy," He has said, "dangerous atheism." He has given little preference to Buddhism, but to Māyāvāda philosophy He has stated, "It is dangerous atheism." His exact version is like that, bheda namiya bauddha haila nāstika. Vedāśraye nāstika-vāda bauddha ke adika. He says that "We call the Buddhists as atheists because the simple reason is that they do not accept Vedas." Lord Buddha, he denied, that "I don't care for the Vedas. I have got my this own proposition, that ahiṁsā. Nonviolence is the religion. That's all." So he did not accept Vedas. Therefore, those who are Vedantists, those who are followers of Vedas, they called Buddhist religion atheism. Atheism means anyone who does not believe in scriptures, standard scriptures. That is called atheism.
