“Out of many thousands among men, one may endeavor for perfection, and of those who have achieved perfection, hardly one knows Me in truth.” (Lord Krishna, Bhagavad-gita, 7.3)

“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.” (Lord Krishna, Bhagavad-gita, 8.15)
