The Supreme Personality of Godhead said: My dear Uddhava, Brahmā himself, who is born directly from the body of the Lord and who is the creator of all living entities within the material world, being the best of the demigods, seriously contemplated the question of his sons headed by Sanaka. The intelligence of Brahmā, however, was affected by his own activities of creation, and thus he could not discover the essential answer to this question.
