Remain centred, in control of your senses. Do not let your senses be in control of you. Observe the sense data as it comes to you. See through your eyes, not with them. Do not be drawn towards the gates of the senses where you will be sucked outside, and become absorbed in the outside world.
With the wisdom of the Infinite, look at things and then "reject" them. As one concept arises after another, reject. When you see an object, look past its edges. As you wrathfully reject all, practicing un-thinking, you will break through to the clear-light and see All. This is the beginning.
