“Most humans are still, almost literally, possessed by thought. They don’t think, but thinking happens to them. The beginning of spiritual awakening is the realization that you are not the voice in your head but the one who is aware of the voice. You are the awareness behind your thoughts. As this realization grows, you begin to derive your sense of identity increasingly from the space of awareness rather than from the narratives in your mind. You are letting go of the identification with thought. Thought is no longer imbued with self!
That is the ultimate letting go, the only true renunciation. You are still able to enjoy external things such as possessions and sensory pleasures, but they lose their overriding importance and their addictive nature. You enjoy them with a sense of detachment, while they last. (Spoiler alert: they won’t last!) You don’t seek yourself in them anymore. Life sheds its absolute seriousness.
What is the criterion for progress on this path? Thought increasingly loses its capacity to make you unhappy! You are less reactive in the face of challenging situations or people. You recognize worry as futile and destructive, so you are able to let it go when it happens. You find inner peace and contentment in the present moment. And perhaps you begin to realize that you are not a person but an essential and intrinsic part of the evolution of universal consciousness.”
