The Māyāvādī philosophers stress the statements tat tvam asi, so ’ham, etc., but they do not stress the real mahā-mantra, praṇava (oṁkāra). Therefore, because they misrepresent Vedic knowledge, they are the greatest offenders to the lotus feet of the Lord. Caitanya Mahāprabhu says clearly, māyāvādī kṛṣṇe aparādhī: “Māyāvādī philosophers are the greatest offenders to Lord Kṛṣṇa.” Lord Kṛṣṇa declares:

tān ahaṁ dviṣataḥ krūrān saṁsāreṣu narādhamān
kṣipāmy ajasram aśubhān āsurīṣv eva yoniṣu

“Those who are envious and mischievous, who are the lowest among mankind, I perpetually cast into the ocean of material existence, into various demoniac species of life.” (Bg. 16.19) Life in demoniac species awaits the Māyāvādī philosophers after death because they are envious of Kṛṣṇa. When Kṛṣṇa says in the Bhagavad-gītā (9.34) man-manā bhava mad-bhakto mad-yājī māṁ namaskuru (“Engage your mind always in thinking of Me, become My devotee, offer obeisances to Me and worship Me”), one demoniac scholar says that it is not Kṛṣṇa to whom one must surrender. This scholar is already suffering in this life, and he will have to suffer again in the next if in this life he does not complete his prescribed suffering. One should be very careful not to be envious of the Supreme Personality of Godhead. In the next verse, therefore, Śrī Caitanya Mahāprabhu clearly states the purport of the Vedas.
