Upon being informed by Lord Śiva, mother Pārvatī could understand that she was wrong in cursing Citraketu. King Citraketu was so exalted in his character that in spite of being wrongly cursed by Pārvatī, he immediately descended from his airplane and bowed his head before the mother, accepting her curse. This has already been explained: nārāyaṇa-parāḥ sarve na kutaścana bibhyati. Citraketu very sportingly felt that since the mother wanted to curse him, he could accept this curse just to please her. This is called sādhu-lakṣaṇam, the characteristic of a sādhu, or a devotee. As explained by Śrī Caitanya Mahāprabhu, tṛṇād api sunīcena taror api sahiṣṇunā. A devotee should always be very humble and meek and should offer all respect to others, especially to superiors. Being protected by the Supreme Personality of Godhead, a devotee is always powerful, but a devotee does not wish to show his power unnecessarily. However, when a less intelligent person has some power, he wants to use it for sense gratification. This is not the behavior of a devotee.
