sri-bhagavan uvaca -- the Supreme Personality of Godhead said; jita-indriyasya -- of one who has conquered his senses; yuktasya -- who has steadied the mind; jita-svasasya -- and conquered his breathing system; yoginah -- of such a yogi; mayi -- in Me; dharayatah -- fixing; cetah -- his consciousness; upatishthanti -- appear; siddhayah -- the mystic perfections of yoga.
There are eight primary mystic perfections, such as anima-siddhi, and ten secondary perfections. In this Fifteenth Chapter Lord Krishna will explain that such mystic perfections are actually impediments to the development of Krishna consciousness, and that therefore one should not desire them.
