BRS 2.1.193

The eight great siddhis [Note: Among the eight primary mystic perfections, the three by which one transforms one’s own body are aṇimā, becoming smaller than the smallest; mahimā, becoming greater than the greatest; and laghimā, becoming lighter than the lightest. Through the perfection of prāpti one acquires whatever one desires, and through prākāmya-siddhi one experiences any enjoyable object, either in this world or the next. Through iśitā-siddhi one can manipulate the subpotencies of māyā, and through the controlling potency called vaśitā-siddhi one is unimpeded by the three modes of nature. One who has acquired kāmāvasāyitā-siddhi can obtain anything from anywhere, to the highest possible limit. My dear gentle Uddhava, these eight mystic perfections are considered to be naturally existing and unexcelled within this world. SB 11.15.4-5] are served (vṛtā) by ten siddhis [Note: The ten secondary mystic perfections arising from the modes of nature are the powers of freeing oneself from hunger and thirst and other bodily disturbances, hearing and seeing things far away, moving the body at the speed of the mind, assuming any form one desires, entering the bodies of others, dying when one desires, witnessing the pastimes between the demigods and the celestial girls called Apsaras, completely executing one’s determination and giving orders whose fulfillment is unimpeded. SB 11.15.6-7] one after the other. The siddhis may be known from the Eleventh Canto.
