With practices such as meditation, one begins to see the self as an illusion. This is the core of spiritual teachings. Many times while meditating I've experienced a detachment where it feels as if something outside myself is looking through me. Such a state is achieved by overcoming the serpents of distraction the ego throws at you. The goal of meditation and yoga is to see through the self and dive into the inner universe.
