Lord Siva, speaking to Parvati-devi, foretold that he would spread the Mayavada philosophy in the guise of a sannyasi brahmana just to eradicate Buddhist philosophy. This sannyasi was Sripada Sankaracarya. In order to overcome the effects of Buddhist philosophy and spread Vedanta philosophy, Sripada Sankaracarya had to make some compromise with the Buddhist philosophy, and as such he preached the philosophy of monism, for it was required at that time. Otherwise there was no need for his preaching Mayavada philosophy. At the present moment there is no need for Mayavada philosophy or Buddhist philosophy, and Lord Caitanya rejected both of them. This Krsna consciousness movement is spreading the philosophy of Lord Caitanya and rejecting the philosophy of both classes of Mayavadi. Strictly speaking, both Buddhist philosophy and Sankaras philosophy are but different types of Mayavada dealing on the platform of material existence. Neither of these philosophies has spiritual significance. There is spiritual significance only after one accepts the philosophy of Bhagavad-gita, which culminates in surrendering unto the Supreme Personality of Godhead. Generally people worship Lord Siva for some material benefit, and although they cannot see him personally, they derive great material profit by worshiping him.
