There is no such thing as the "I," one cannot live for his-self, whether "He” is an individual, a family, a community, a nation or a race. It is not truth and therefore such separation will go, even though it will take a long time.
There is necessity of renouncing ignorance is born of an illusion, an erroneous belief in the reality of a separate "me": those who realize that consciousness is everywhere in everything are no longer separate from others and the universe. One cannot really separate himself from universe because man and universe appear together and they disappear together.
Realizing the difference between the seen [waking/dream] and the formless witness/soul, when the soul gets disunited from `seen [waking/dream]' and established in identity with itself, which is the supreme Spirit, one is said to have known liberation from duality.
While dreaming one is being reminded his waking state, he comes to recognize the dream, therefore, he wake up. Immediately he realizes that waking is the only means of escape from the woes of the dream state.
Even so the seeker of truth following the path of self-Knowledge, while perceiving the difference between the Seen [waking/dream] and the Formless Witness [soul/self], comes to realize the apparent connection with the Seen was due to mistaken identity.
The seeker is able to re-establish the real connection and recognizes real identity [soul]. – The Truth, Consciousness and Bliss solidified. Such a seeker is said to have come to know his /her liberation from duality. The moment this truth is realized, the entire realm of objective reality becomes unreality along with ignorance and Truth -Realization takes place immediately.
