Knowledge of Brahman is so intensely fascinating that it is the be-all and end-all of existence.
One needs to experience Reality in all its dimensions to get to realise what lies beyond simple existence of the body-brain-mind complex in order to appreciate what I know is fascinating complexities of the mental faculties that one potentially possesses and through further exploration see that it is part of a Grand Design to be individually fathomed. It is not for communal appreciation. Being Brahman has tremendous practical significance in conducting oneself during one's life for it is truth and truth is all powerful in combatting the elements of Brahma-Nature that threaten survival in the dignity of liberty. In Brahman, the Self operates nonchalantly, spontaneously and unpremeditatedly without aims, ambitions, missions, plans, objectives, expectations, anticipations, hopes, wishes, desires and the ego (the most self-destructive part of existence). When one transcends the mind into the mental faculty of the atman, one attains freedom, liberation and total peace of mind, even bliss, and such is the confidence with which one goes about one's life that one is unperturbed by the events that cause suffering in others concerned with the mundane existence. One has peace of mind.
The Self is the spokesperson for Brahman.
One is Brahman when one sees that perfection is personified in one's actions for then pristine truth dawns in one to aid one's survival in liberty.
