ya Ätma-vidyÄm ÄkhyÄya svayaá¹ samÅ›uddho mahÄ-puruá¹£am anusasmÄra
yaḥ - who (King PratÄ«ha); Ätma-vidyÄm ÄkhyÄya - after instructing many people about self-realization; svayam - personally; samÅ›uddhaḥ - being very advanced and purified in self-realization; mahÄ-puruá¹£am - the Supreme Personality of Godhead, Viṣṇu; anusasmÄra - perfectly understood and always remembered.
The word anusasmÄra is very significant. God consciousness is not imaginary or concocted. The devotee who is pure and advanced realizes God as He is. MahÄrÄja PratÄ«ha did so, and due to his direct realization of Lord Viṣṇu, he propagated self-realization and became a preacher. A real preacher cannot be bogus; he must first of all realize Lord Viṣṇu as He is. As confirmed in Bhagavad-gÄ«tÄ (4.34), upadeká¹£yanti te jñÄnaá¹ jñÄninas tattva-darÅ›inaḥ: “One who has seen the truth can impart knowledge.†The word tattva-darśī refers to one who has perfectly realized the Supreme Personality of Godhead. Such a person can become a guru and propound Vaiṣṇava philosophy all over the world. The paragon of bona fide preachers and gurus is King PratÄ«ha.
