SB 6.4.43, Translation and Purport

The Supreme Personality of Godhead said: O most fortunate Prācetasa, 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.

As the Lord Himself confirms in Bhagavad-gītā (BG 8.15), one reaches the highest perfection when he attains the fortune of realizing the Supreme Personality of Godhead:

mām upetya punar janma

duḥkhālayam aśāśvatam

nāpnuvanti mahātmānaḥ

saṁsiddhiṁ paramāṁ gatāḥ

"After attaining Me, the great souls, who are yogīs in devotion, never return to this temporary world, which is full of miseries, because they have attained the highest perfection." Therefore the Kṛṣṇa consciousness movement teaches one to follow the path toward the topmost perfection simply by performing devotional service.
