As She played with the ball, the sari covering Her body became loose, and Her hair scattered. She tried to bind Her hair with Her beautiful left hand, and at the same time She played with the ball by striking it with Her right hand. This was so attractive that the Supreme Lord, by His internal potency, in this way captivated everyone.
In Bhagavad-gītā (7.14) it is said, daivī hy eṣā guṇa-mayī mama māyā duratyayā: the external potency of the Supreme Personality of Godhead is extremely strong. Indeed, everyone is fully captivated by her activities. Lord Śambhu (Śiva) was not to be captivated by the external potency, but because Lord Viṣṇu wanted to captivate Him also, He exhibited His internal potency to act the way that His external potency acts to captivate ordinary living entities. Lord Viṣṇu can captivate anyone, even such a strong personality as Lord Śambhu.
