To know whole truth, one must know all the three states are one in essence and also the form, time and space are one is essence . Without realizing this truth Self-knowledge or Brahma Gnana or Atma Gnana is impossible. There is no use of convincing anyone because they will never get convinced until they hold their own yardstick.
Ultimate truth is attainable by anyone who has intense urge and humility and ready to investigate and make sure “what is truth” and ‘what is untruth’ and mentally drop the untruth to establish in the truth with full and firm conviction.
Truth is “What is this waking “What this dream? What is the deep sleep? ” “What is the meaning of life as a whole?" The ultimate truth or Brahman can be realized only through soul-centric reasoning not through intellectual argument, because intellectualism is limited to individuality.
The ultimate truth 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. But if a serious seeker strives by means of inquiry, analysis and reasoning on the true base, he will be able to realize it.
By realizing consciousness, one becomes satisfied with that Knowledge. He establishes in the true self, and he is free from experiencing the duality as reality and he is in non-dual self-awareness. Such seeker ever devoted to the Self, behold everywhere the consciousness.
Having well ascertained the Self- knowledge or Brahma Gnana or Atma Gnana and having perfect understanding,assimilation and realization one reaches the supreme goal of freedom. The seekers, never relaxing their efforts, enjoy here supreme Immortality and at the time of the great end attain complete freedom in consciousness.
When one realizes the fact that, the causes of all the causes is uncaused; and views and judges the worldview on the base of the uncaused, then everything of the experience of duality, becomes one with the highest imperishable consciousness, which is the Self of all.
As flowing rivers disappear in the sea, losing their names and forms, so one is freed from name and form, attains the Atman, which is greater than the Great.
He who knows the Atman as self verily becomes consciousness. He overcomes the experience of duality; becomes one with the Atman, the immortal self, which is present in the form of consciousness.
