The word brāhmaṇa-mūrtinā in this verse refers to the founder of Māyāvāda philosophy, Śaṅkarācārya, who was born in the Mālabara district of southern India. Māyāvāda philosophy states that the Supreme Lord, the living entities and the cosmic manifestation are all transformations of illusory energy. To support this atheistic theory, the Māyāvādīs cite false scriptures, which make people bereft of transcendental knowledge and addicted to fruitive activities and mental speculation.
This verse is a quotation from the Padma Purāṇa, Uttara-khaṇḍa (25.7).
