What is the inner meaning of an eclipse and the bath after eclipse?

The Lord distributed the divine nectar in human form as Mohini. The human incarnation can be male or female. The sun and the moon are the planets with light, which indicates knowledge. They gave a hint to the Lord that a demon is stealing the divine nectar in disguise [by going through an eclipse]. This means that even deities become ignorant. Is there a necessity to give a hint to the Lord who knows everything? When the Lord is in human form, even deities think that He does not know everything! This is their ignorance. Such ignorance of knowledge is the real eclipse. Rahu and Ketu are called as the planets of Tamas or darkness, which represents ignorance. Such ignorance is [symbolically] washed away by taking the bath over the head after the eclipse.
