SB 8.13.13
dattvemam yacamanaya
visnave yah pada-trayam
raddham indra-padam hitva
tatah siddhim avapsyati
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Bali Maharaja gave a gift of three paces of land to Lord Visnu, and because of this charity he lost all the three worlds. Later, however, when Lord Visnu is pleased because of Bali’s giving everything to Him, Bali Maharaja will achieve the perfection of life.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In Bhagavad-gita (7.3) it is stated, manusyanam sahasresu kascid yatati siddhaye: out of many millions of people, one may attempt to achieve success in life. This success is explained here. Raddham indra-padam hitva tatah siddhim avapsyati. Siddhi consists of achieving the favor of Lord Visnu, not the yoga-siddhis. The yoga-siddhis — anima, laghima, mahima, prapti, prakamya, isitva, vasitva and kamavasayita — are temporary. The ultimate siddhi is to achieve the favor of Lord Visnu.
