विकारिणां सर्वविकारवेत्तानित्योऽविकारो भवितुं समर्हति ।मनोरथस्वप्नसुषुप्तिषु स्फुटंपुनः पुनर्दृष्टमसत्त्वमेतयोः ॥ २९६ ॥
In plain words
Whatever witnesses every change in changing things must itself be changeless and eternal — that only stands to reason. And notice: in daydream, in dream, and in deep sleep, the unreality of the body and ego we take so seriously shows itself clearly, again and again.
Close to the Sanskrit
The knower of all changes in changing things must logically be eternal and unchanging. In daydream, dream, and deep sleep, the unreality of these two, the body and the ego, is clearly seen again and again.
