There is a civil service examination before one man is posted in some responsible office. Similarly, to be recognized by Krsna, as He says, na ca tasman manusyesu [Bg. 18.69], one has to pass examination, severe test of examination. All the big, big devotees we see. Narada Muni, before becoming Narada Muni, he had to pass through severe examination, test. So that chance is there in the human form of life, to pass the examination, test.
