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.
So Caitanya Mahāprabhu says that Buddha philosophy is atheism undoubtedly, but Śaṅkara philosophy is dangerous atheism because he is accepting Vedānta, but he is preaching atheism. He's accepting... Under the shelter of Vedānta, he's preaching atheism. So therefore they are more dangerous. Just like you are fighting with your enemies, that is very clear. "The other party is my enemy." But if somebody's treating as your friend and within he's trying to kill you, enemy, oh, that is very dangerous enemy. So similarly, Caitanya Mahāprabhu said that Buddhism is atheism. That's all right. But this Śaṅkara's philosophy is more dangerous than atheism. And actually, so-called, so many swamis and sannyāsīs, they came. They come from India. They are this same, dangerous atheists. Nobody has preached in your country this philosophy of Kṛṣṇa consciousness or... Bhagavad-gītā is widely read, but differently interpreted. So therefore they are dangerous atheists. They are... Under the garb of Bhagavad-gītā, they are preaching atheism. So they are very dangerous. But still, because he was Lord Śiva, incarnation of Lord Śiva, and he had a particular duty, therefore Caitanya Mahāprabhu supports now that tāṅhāra nāhika doṣa: "He's not faulty. He's not faulty because the time required to propagate such philosophy, and he had done that under the order of the Supreme Personality of Godhead. He wanted."
