jita-indriyasya -- of one who has conquered his senses; dantasya -- who is disciplined and self-controlled; jita-svasa -- who has conquered his breathing; atmanah -- and conquered the mind; muneh -- of such a sage; mat -- in Me; dharanam -- meditation; dharayatah -- who is conducting; ka -- what is; sa -- that; siddhih -- perfection; su-durlabha -- which is very difficult to achieve.
For a sage who has conquered his senses, breathing and mind, who is self-controlled and always absorbed in meditation on Me, what mystic perfection could possibly be difficult to achieve?
Srila Sridhara Svami comments as follows. "Lord Krishna here expresses that there is no need to practice many different processes, for by completely carrying out even one of the above-mentioned procedures one controls one's senses, becomes absorbed in Him and thus achieves all mystic perfections."
Srila Jiva Gosvami notes that one must meditate on the transcendental form of the Lord, which is free from any material designation. This is the essence of advancing in the yoga system; thus one acquires all mystic perfections very easily from the personal body of the Personality of Godhead.
