Srimad Bhagavatam: C-02, Ch-6, #34
Srimad Bhagavatam: Canto 2, Chapter 6, text 34
34. O Narada, because I have caught hold of the lotus feet of the Supreme Personality of Godhead, Hari, with great zeal, whatever I say has never proved to have been false. Nor is the progress of my mind ever deterred. Nor are my senses ever degraded by temporary attachment to matter.
35. Although I am known as the great Brahma, perfect in the disciplic succession of Vedic wisdom, and although I have undergone all austerities and am an expert in mystic powers and self realization, and although I am recognized as such by the great forefathers of the living entities, who offer me respectful obeisances, still I cannot understand Him, the Lord, the very source of my birth.
36. Therefore it is best for me to surrender unto His feet, which alone can deliver one from the miseries of repeated birth and death. Such surrender is all-auspicious and allows one to perceive all happiness. Even the sky cannot estimate the limits of its own expansion. So what can others do when the Lord Himself is unable to estimate His own limits?
