ya atma-vidyam akhyaya svayam samsuddho maha-purusam anusasmara.
yah—who (King Pratiha); atma-vidyam akhyaya—after instructing many people about self-realization; svayam—personally; samsuddhah—being very advanced and purified in self-realization; maha-purusam—the Supreme Personality of Godhead, Visnu; anusasmara—perfectly understood and always remembered.
King Pratiha personally propagated the principles of self-realization. In this way, not only was he purified, but he became a great devotee of the Supreme Person, Lord Visnu, and directly realized Him.
The word anusasmara is very significant. God consciousness is not imaginary or concocted. The devotee who is pure and advanced realizes God as He is. Maharaja Pratiha did so, and due to his direct realization of Lord Visnu, he propagated self-realization and became a preacher. A real preacher cannot be bogus; he must first of all realize Lord Visnu as He is. As confirmed in Bhagavad-gita (4.34), upadeksyanti te jnanam jnaninas tattva-darsinah: “one who has seen the truth can impart knowledge.” The word tattva-darsi refers to one who has perfectly realized the Supreme Personality of Godhead. Such a person can become a guru and propound Vaisnava philosophy all over the world. The paragon of bona fide preachers and guru is King Pratiha.
