As person perceiving the world one is unaware of , because he thinks his body as body, his ego as ego his experience of the ,world as world but never he is unaware of the truth they are just mirage created out consciousness due to ignorance of the truth .
Words are needed until one gets firm conviction of ‘what is what. People need reading and hearing the words to think deeply and reach the ultimate end.
People fail to understand that, the emptiness is the nature of the self, which is consciousness. When self becomes aware of its formless non-dual nature it becomes empty of ignorance or illusion or duality or experience of waking or dream. Thus whatever remains empty of duality or ignorance or illusion is non-dual reality. Only through wisdom one becomes aware of the truth in the midst of duality.
That is why Sage Sri, Sankara said: 63_(VC)- Without causing the objective universe to vanish and without knowing the truth of the Self, how is one to achieve Liberation.
The universe will not remain as reality when wisdom dawns. Universe is mere mirage created out of consciousness and there is unity in diversity because there is no second thing exist other than consciousness.
One thinks he is imprisoned within this body; whereas the body and his experience of the world are within the mind. The consciousness is hidden within the three states but it is without the three states. The one, which has the awareness of the three states, is not the body but the soul, which is in the form of consciousness. Thus consciousness is not limited to waking experience alone because it pervades all the three states. Till one views and judges the world-view on base of ego he is in the grip of individuality or intellectuality. The self is not an individual because it is universal. And it pervades in everything and everywhere in all the three states. Thus individualized judgment will not lead one non-dual destination.
That is why Sage Sri, Sankara says in (VC)-65:- As a treasure hidden underground requires (for its extraction) competent instruction, excavation, the removal of stones and other such things lying above it and (finally) grasping, but never comes out by being (merely) called out by name, so the transparent Truth of the self, which is hidden by Maya and its effects, is to be attained through the instructions of a knower of Brahman, followed by reflection, meditation and so forth, but not through perverted arguments.
66. Therefore the wise should, as in the case of disease and the like, personally strive by all the means in their power to be free from the bondage of repeated births and deaths.
Thus, one has to know what is real by realizing his body and his experience of the world are mere illusion created out of the formless soul, the innermost self. . soul is present in the form of consciousness. The nature of the self is emptiness because it is formless . And it is identified by different masters with different name, such as Brahman, Buddha’s nature, Christ consciousness, Self, Ultimate Truth.
Self-knowledge or Atma Gnana or Brahma Gnana cannot be attained by one who is without strength or earnestness or without the receptiveness and courage to accept the truth and reject the untruth. If a serious seeker strives sincerely by means of inquiry, analysis and soul-centric reasoning, he will be able to realize it.
It is only seekers sincerity and earnestness in his spiritual pursuit, the knowledge started revealing on its own. Anyone who has humility and patience and is sincere and ready to drop their accumulated dross and receptive to accept the truth will enter non-dual Self-Awareness when his conviction becomes firm.
