All of these aspects of identity are invisible, known to us as thoughts and flows in our energy body. (No one will ever find your identity in an autopsy.) It’s as if we are a computer shifting all of this data around. When kundalini opens and begins to move through the system it is challenging and disorienting, as it clears away much of our identity, opening our body to a different kind of experience, one we might call prior to identification. It will eventually lead us to know ourselves as awareness without identity, which is a knowing that feels eternal in nature, and free of the stuck patterns in our history. It can be very frightening to feel something in us letting go of us. In western cultures we tend to believe this must be a sign of mental illness, but when kundalini is the catalyst it is a sign of spiritual awakening.
