CC Ādi 14.36

eimate nānā-chale aiśvarya dekhāya
bālya-bhāva prakaṭiyā paścāt lukāya
eimate — in this way; nānā-chale — under different excuses; aiśvarya — opulence; dekhāya — exhibits; bālya-bhāva — the status of a child; prakaṭiyā — manifesting; paścāt — thereafter; lukāya — hides Himself.
Thus under various excuses the Lord exhibited His opulences as much as possible in His childhood, and later, after exhibiting such opulences, He hid Himself.
