SB 6.4.43
sri-bhagavan uvaca
pracetasa maha-bhaga
samsiddhas tapasa bhavan
yac chraddhaya mat-paraya
mayi bhavam param gatah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The Supreme Personality of Godhead said: O most fortunate Pracetasa, because of your great faith in Me, you have attained the supreme devotional ecstasy. Indeed, because of your austerities, combined with exalted devotion, your life is now successful. You have achieved complete perfection.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
As the Lord Himself confirms in Bhagavad-gita (8.15), one reaches the highest perfection when he attains the fortune of realizing the Supreme Personality of Godhead:
mam upetya punar janma
duhkhalayam asasvatam
napnuvanti mahatmanah
samsiddhim paramam gatah
“After attaining Me, the great souls, who are yogis in devotion, never return to this temporary world, which is full of miseries, because they have attained the highest perfection.” Therefore the Krsna consciousness movement teaches one to follow the path toward the topmost perfection simply by performing devotional service.
