Awareness

Be aware of your heart and mind. Be watchful of it. See how it rises and falls, at one moment in bliss and another moment in chaos. Judge not a moment of any states, but recognize it as part of one. Attach not to any moment. Let go. Let be.
Every troubled moment is caused by holding onto something, whether a thought, an ideal or an expectation. Become aware of what you are holding onto, and free yourself from it.

Know this: You are the creator and destroyer of your own life and all your experiences.
