In plain words
O Śrī Kāmākṣī, when the shoot of light of your lovely gentle smile has risen to the rank of emperor over the vast realm of whiteness, this moon takes the rank of crown prince, moonlight serves as handmaid, and the pure stream of nectar takes on the role of companion.
Word for word
Śrī Kāmākṣī, at the lovely-gentle-smile-light-sprout your vast-whiteness-emperor-way-boldness having attained, the moon this the heir-apparent-ship takes, the handmaid-burden moonlight, pure that and nectar-stream companion-likeness takes on.
