"Our egos are naturally reluctant to relinquish the familiar mode of functioning. We do not want to give up the illusion of our enduring separate selfhood, which we so laboriously learned to define, cultivate, and rely on for most of our conscious lives. Even if we understand that letting go of our attachment to the known will bring freedom from suffering, attempts at doing so deliberately and on one’s own are mostly ineffective and always lead to intractable paradoxes. The more one becomes attached to the idea of non-attachment, the more firmly one remains fettered. The more one is conscious and proud of one’s psychic powers and ego-transcending quest, the more clearly one’s ego is still enthroned."
