Srimad Bhagavatam Canto 01, Chapter 03, Text 39

SB 1.3.39

atheha dhanya bhagavanta ittham
yad vasudeve ’khila-loka-nathe
kurvanti sarvatmakam atma-bhavam
na yatra bhuyah parivarta ugrah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Only by making such inquiries in this world can one be successful and perfectly cognizant, for such inquiries invoke transcendental ecstatic love unto the Personality of Godhead, who is the proprietor of all the universes, and guarantee cent-percent immunity from the dreadful repetition of birth and death.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
The inquiries of the sages headed by Saunaka are herewith praised by Suta Gosvami on the merit of their transcendental nature. As already concluded, only the devotees of the Lord can know Him to a considerable extent, and no one else can know Him at all, so the devotees are perfectly cognizant of all spiritual knowledge. The Personality of Godhead is the last word in Absolute Truth. Impersonal Brahman and localized Paramatma (Supersoul) are included in the knowledge of the Personality of Godhead. So one who knows the Personality of Godhead can automatically know all about Him, His multipotencies and His expansions. So the devotees are congratulated as being all-successful. A cent-percent devotee of the Lord is immune to the dreadful material miseries of repeated birth and death.
