The non-dual bliss is not an individual experience but it is the nature of the consciousness, which is the true self.

Investigation of the Self and Investigations of the 3 states of existence - waking, sleeping, deep sleep the self has a single unitary existence; its inherent nature is "Existence, Consciousness and Bliss". Universe and its contents are truly this at its core, but have seemingly forgotten about their true nature, in the present state of duality, which is caused by ignorance of the reality.

The non-dual bliss is not an individual experience but it is the nature of the consciousness, which is the true self.  Consciousness pervades all the three states thus the self is not limited to the waking entity or waking world or dream entity or dream world.  Consciousness is the formless witness of all the three states and witnesses the waking or dream experience as a whole without the physical apparatus.

This uninterrupted Blissful awareness  is achievable by every being in this life itself, once he/she realizes this and works towards discarding the "unreal” by discriminating between real and unreal mentally.

Consciousness, which is the “true self”, does not have birth, life and death. It has not taken birth and it will not take birth. It is beyond birth, life and death, it is immortal, and it is ancient, it does not perish when the mind, which is in the form of universe, perishes. The universe or mind is like the wave of the see but not the sea, which is the “true self” or consciousness.

Consciousness cannot be cut, cannot be burnt, cannot be melted; neither can be dried. It is eternal, unmovable, unlike the universe or mind which perishes.   It is the cause of duality. It is the consciousness or self, which oversees the duality or the universe or the mind.  

The consciousness projects itself as the inherent power of the universe.  The self-i.e., Consciousness is the essence of all happenings and circumstances in, which the seeker attempts to know the truth of his true existence.
