Consciousness is the only reality; this universe, which is in the form of mind, is not real; the mind is nothing else but consciousness itself because it is erupted out of consciousness.
Formless Consciousness is Absolute Principle, One without second, and a Totality emanating oneness. The supreme goal of Seeker is to discover the truth of his true existence. What is true nature of the mind and how liberation from mind, which is in the form of universe, can be achieved?
The consciousness neither born, nor lives nor dies because it is birthless. This truth not recognized by seekers because they were unable to lift their consciousness and realize the non-dual reality.
If the goal is the attainment of the non-dual truth, then a well-directed inquiry, analysis and reasoning is altogether sufficient.
Consciousness is an unchangeable Reality, eternal, in act, with no generation and extinction, free of cause-effect and form, time-space, devoid of contradiction, One-without-a-second; and, as Reality is constant and perfect Unity.
Only when viewed from the standpoint of physical self, the all differentiation, multiplicity, impermanence becomes reality.
When viewed from the standpoint of "consciousness", which is ultimate truth, all differentiation, multiplicity, impermanence becomes unreality. Thus the universe is always in the nature of change cannot be the ultimate Reality but only appearance and its reality will prevail until ignorance dominates. And when wisdom dawns the ignorance vanishes and the reality prevail.
From the standpoint of the consciousness as self, which the One-without-a-second and a one comes to the conclusion that the consciousness is the ultimate truth: there is neither birth nor life and nor death, no universe, no aspirant to liberation and no liberated, no duality or diversity, everything is one and there is only oneness.
The true self is self-existing and free form all attributes and duality, which are pure Consciousness, Infinite and Fullness. It can be realized only by identifying the formless substance and witness of the three states as the self.
By holding the formless witness as true self and the negation of all the three states mentally, one become aware of the fact that, the changeable [three states] or, in other words, that belongs to the illusion or universe or appearance. This substrate is consciousness, which is reflected in all the three states as their formless substance witness, and is "One-without-a-second".
