The real 'I' is beyond birth and death, does not feel hungry or thirsty, is free from misery and sense of pelf and possession and is simply a witness to all activities of the mind-body-ego-knot. All acquisition of knowledge or information in this world is subject to our personal experience. Therefore it is always subjective and relative to our physical body, till we become aware of our true identity. Then and only then we get clear vision about our roles as embodied spiritual seekers. Therefore, awakened awareness of Self or Self-Realization is the supreme aim of human life.
