When the Supreme Personality of Godhead assumed the form of the beautiful woman Mohinī-mūrti, the demons were certainly captivated, but the demigods present were not. In other words, those who maintain a demoniac mentality are bewildered by the beauty of a woman, but those who are advanced in Kṛṣṇa consciousness, or even those on the platform of goodness, are not bewildered. The Supreme Personality of Godhead knew that because Lord Śiva is not an ordinary person, he cannot be bewildered even by the most beautiful woman. Cupid himself tried to invoke Lord Śiva’s lusty desires in the presence of Pārvatī, but Lord Śiva was never agitated. Rather, the blazing fire from Lord Śiva’s eyes turned Cupid to ashes. Therefore, Lord Viṣṇu had to think twice about what kind of beautiful form would bewilder even Lord Śiva. Consequently He was smiling gravely, as stated in the previous verse ( prahasya bhāva-gambhīram ). A beautiful woman generally cannot induce Lord Śiva to be lusty, but Lord Viṣṇu was considering whether there was any form of woman who could enchant him.
