What is the advanced state of 'Nivrutti' or cessation, and how does it fundamentally alter an individual's experience of reality and self?

The state of Nivrutti, or cessation, is described in Chapter 17 as the end of worldly inclination, which occurs when the knowledge of the Self is attained. This profound shift happens when the tendency of bodily ego dissolves completely. In this state, the individual's soul realizes its identity with the Supreme Self. The perception of reality is transformed; as one sees only the Self everywhere, the concepts of 'enemies' and 'friends' cease to exist. This brings a supreme happiness before which all worldly sorrows and pleasures seem miserable and insignificant.
