Without remaining open to change , we can not remain open to life
It's very hard to grow, because it's difficult to let go of the models of ourselves in which we've invested so heavily.
Meditation means to be constantly extricating yourself from the clinging of mind. By letting go of even the thought 'I,' and 'me' what is left? There is nowhere to stand and no one to stand there. No separation anywhere. Pure awareness. Neither this, nor that. Just clarity and being.
The offering up or cleaning up ego stuff is called purification. Purification is the act of letting go. This is done out of discriminative awareness. That is, you understand that you are an entity passing through a life in which the entire drama is an offering for your awakening.
