Mundaka Upanishad:~ As rivers flow into the sea and in so doing lose name and form, so even the wise man, freed from name and form, attains the Supreme Being, the Self-luminous, the Infinite. He who knows Brahman becomes Brahman. ~ 3.2.8 

The seeker after the truth should take to soul-centric reasoning and discriminate between dual and non-dual experiences to realize 'what the truth' is and 'what is untruth'. 

Swami Vivekananda: ~ “Advaita encompasses everything. Since Advaita requires heavy-duty intellectualism, it had to be progressively simplified.

First one must inquire into the nature of the 'I' i.e. matter. Second, he must inquire into the nature of the mind, which is in the form of the universe.

One has to realize by looking at everything in nature because in everything there is consciousness. One should not avoid them, he should not shut his eyes to Nature; he should not shut himself away from the world which is as much consciousness, as anything else.

But those who are ignorant tell one to be non-observant and to withdraw: keen powers of observation are desirable and will help, not hinder one’s pursuit of truth. One has to take experiences as they come to him and he should not run away from the world in ascetic fear or shyness of them.

To say they are an illusion without first examining them and inquiring into them thoroughly is to delude oneself. This world is common to everyone; therefore one must begin his inquiry with it and not avoid it. It is only after he has inquired into the nature of the objective universe, that he should inquire into who is the knower. If, however he inquiries into the knower before the inquiry into the universe, then it is mere mysticism. “What is this universe?” must precede “What is’ I”?”   in pursuit of truth.

In the witness state, consciousness is aware of both conscious and unconscious. But in waking or dream it is unconscious of its true nature and conscious of the individuality which perceives the world.   In deep sleep, it is without individuality and the world.  There is no burden and bondage in deep sleep. There is gravity in deep sleep. It is unconsciously complete un- connectedness to the world.  Becoming consciously un-connectedness to the world in the midst of waking experience is the witness state.  To achieve this one has to drop all accumulate dross based on the ego as self.    

This witness states is the state of Brahman which is free from all the burden and bondage of the universe, which is the dualistic illusion or Maya. It is free from the illusory experience of birth, life, death, and the world.  It is free of illusory pain and pleasure. It is free from illusory duality and it is an eternal reality.:~Santthosh Kumaar
