Vidarna swami gives one of the grandest verses in the pancha dashi. He says, masap the ugacal pasho gataga misuncada no detinostamiteka somewa te shasampraa very poetic, stirring, sublime verse. What does an eon a that is? I looked it up, and in it is an actual number. Months pass. Years pass. Lifetimes pass ages. Huga passes. Calpiis an eon. Culpa will pass. We'll see how to apply it. Deep sleep also consciousness continues. It is just the absence of sensory ception is revealed by the consciousness.
"The objects of knowledge, viz., sound, touch, etc., which are perceived in the waking state, are different from each other because of their peculiarities; but the consciousness of these, which is different from them, does not differ because of its homogeneity." Inspired by this verse from the book, Pancadasi by Vidyaranya (Ch 1, Verse 3), Swami Sarvapriyananda gives a discourse on direct path of Advaita Vedanta.
