Can you describe the state of Samadhi and the concept of non-duality as taught by Baba?

In Chapter 19, Baba describes the advanced state of Samadhi as the culmination of contemplation. It is a state of profound peace where the distinction between the meditation and the meditator dissolves, and the mind becomes still, 'like a lamp in a windless place.' This is achieved by becoming free from all desires and realizing that the divine resides in all beings. This realization of non-duality—understanding that the Inner Self, God, and the Guru are one without an atom of difference—leads to fearlessness. Once this state is reached, the bonds of action created by ignorance break apart.
