We realize--often quite suddenly--that our sense of self, which has been formed and constructed out of our ideas, beliefs and images, is not really who we are. It doesn't define us, it has no center.
At each moment we are expressing what we know ourselves to be. If we know ourselves very little we will express and manifest that unconsciousness of our true nature.
If we know who and what we are very thoroughly, we will express and manifest that in what we do.
It is all very simple.
The unknown, our own true nature, has the capacity to wake itself up when you start to fall in love with letting go of all the mental structures you hold onto. Contemplate this: there is no such thing as a true belief.
