TRANSLATION

" 'O supreme great one! O Supreme Personality of Godhead! O Supersoul, master of all mystic power! Your pastimes are taking place continuously in these worlds, but who can estimate where, how and when You are employing Your spiritual energy and performing Your pastimes? No one can understand the mystery of these activities.'

This verse is quoted from Srimad-Bhagavatam (10.14.21).
