The word tantram is significant herein. Sometimes tantram is misunderstood to be the black spiritual science of materialistic persons engaged in sense gratification, but here tantram means the science of devotional service compiled by ÅšrÄ«la NÄrada Muni. One can take advantage of such regulative explanations of the path of devotional service and make progressive advancement in the devotional service of the Lord. SÄá¹…khya philosophy is the basic principle of acquiring knowledge, as will be explained by the sage Maitreya. The SÄá¹…khya philosophy enunciated by Kapiladeva, the son of DevahÅ«ti, is the real source of knowledge about the Supreme Truth. Knowledge not based on the SÄá¹…khya philosophy is mental speculation and can yield no tangible profit.
