In plain words
O Mother Kāmākṣī, your glance is nectar itself: utterly cool, removing the deadly poison of karma ripening without check, and easily won by the good, as nectar is by the gods. There is only one difference: this nectar is blue.
Word for word
Utterly cool, the unchecked-karma-ripening-poison-removing, easy by the good-minded, this nectar indeed your glance, Mother, but, Kāmākṣī, blue this, thus this only the difference.
