“When you are abiding in the nature of mind many different thoughts arise. Thoughts arise because your mind, in addition to being boundless and inexpressible, is full of power and energy, and that power and energy creates, displays, and dissolves thoughts unceasingly. Your mind is active and busy—this is part of its nature. But even though thoughts keep arising nothing changes regarding the nature of your mind. The nature of your mind is empty, and the nature of thought is empty too. If you look into the heart of any thought that arises that thought will dissolve on the spot. Even if you don’t do anything at all the thought will still dissolve. That is why the great master Guru Padmasambhava said that thoughts move through the mind like wind moves through the sky. The wind moves through the sky, in different directions and speeds, stopping and starting, always unpredictable. The wind cannot be separated from the sky, and the sky remains unaffected by the wind. Therefore the high capability practitioner of the highest caliber experiences no difference between abiding and movement. When the mind moves it is fine and when the mind is still it is fine. There are no categories and no choices to be made within the minds of such practitioners.
Observe this for yourself. When you are meditating, how long can your mind abide? Then, when your mind moves, does that movement disturb to you or not?
