The Heart is the Only Reality
7. “The mind now sees itself diversified as the universe. If the diversity is not manifest, it remains in its own essence, that is, the Heart. The Heart is the only reality. The mind is only a transient phase. To remain as one’s Self is to enter the Heart. Entering the Heart means remaining without distractions.” 252
Note: The mind turns into the universe. When it perceives the universe, or diversity, the latter impresses itself on its pure surface, so that its attention is constantly centred on the diversity and not on itself. If the diversity is eliminated, the mind will perceive itself in its essence, its own naked purity. Then it is said to have entered the Heart — in fact it is itself the Heart. This is its undisturbed state, the reposeful state of samadhi.
