"he had never really found his Self, because he had wanted to trap it in the net of thoughts"

The act of thinking or the resulting ideas caused by mental or intellectual activity of an individual's consciousness results in thought.  Consciousness is awareness or wakefulness and ability to experience "feelings” and understand the concept of the True Self.

The Ego, or the superficial/False Self comprises mind and body, is thus, the individual person as the object of his or her own reflective consciousness. The thought process related to the ego-self as delusionary, and Buddhist traditions and practices emphasize on the contemplation of or realization of the True Self as opposed to the False Self or Ego.
