According to the mystics, when we go beyond or transcend our separate-self sense, our limited ego, we discover instead a Supreme Identity, an identity with the All, with universal Spirit, infinite and all-pervading, eternal and unchanging.
As Einstein explains: “A human being is part of the whole, called by us‘Universe’; a part limited in time and space. He experiences himself, his thoughts and feelings as something separated from the rest—a kind of optical delusion of his consciousness. This delusion is a kind of prison for us, restricting us to our personal desires and to affection for a few persons nearest us. Our task must be to free ourselves from this prison.”
Indeed, the whole point of meditation or contemplation—whether it appears in the East or in the West, whether Christian, Muslim, Buddhist, or Hindu—is to free ourselves from the “optical delusion” that we are merely separate egos set apart from each other and from eternal Spirit, and to discover instead that, once released from the prison of individuality, we are one with Godhead and thus one with all manifestation, in a perfectly timeless and eternal fashion.
