Real knowledge means to discriminate between truth and illusion. Jñāna-yoga is the process by which one becomes eternally fixed on the path of transcendental devotional service to the Supreme Lord, who is the source of the Supersoul and Brahman. Jñāna-yoga should never be interpreted to mean the ascending process of enquiry, the inductive method, through which one aims only at separating reality from illusion by gradually rejecting the unreal. It is impossible to attain perfect knowledge without serving the Supreme Lord, who is full with all opulences and potencies, whose bodily luster is the Brahman effulgence, and whose partial expansion is the Supersoul. The brāhmaṇa Gopāla Cakravartī believed that jñāna, perfect knowledge, is far superior to devotional service of the Lord. But as recorded in the Caitanya-caritāmṛta (Antya 3.201):
- balāi-purohita tāre karilā bhartsana
- "ghaṭa-paṭiyā mūrkha tumi bhakti kāṅhā jāna?"
The priest named Balarāma Ācārya chastised Gopāla Cakravartī. "You are a foolish logician," he said. "What do you know about the devotional service of the Lord?"
