We've been talking about "not two," about delight or no delight, about how to end discrimination. This is the way our mind functions--this or that, yes or no, good or bad, sky or earth. Flip, flop. Flip flop in each thought moment. We only see something as opposed to something else.
Want to watch your mind in motion? Tonight, take a few moments and try gazing steadily at this beautiful full moon. Your eyes move ever so slightly from moon to no moon in order to see the moon. Even if you don't want them to move they will anyway. Try it! It is exactly this faculty of comparing that will reveals bodhi to us, so keep observing the mind in action. But know this: Every time you look and perceive its absence, it is because you have also contacted its fullness. All we usually look at is the moon and ignore the space all around it. But if that space were not there, the moon would be hidden from us because everything would be that bright. It's just that this dip back into emptiness goes by so quickly that we miss it. Watch for it tonight. Catch your eyes dipping back into blackness in order to see light. You're watching the operation of just one of your senses--seeing. The other senses work in the same way.
This same space arises between the in breath and the out breath, between heart beats, between awake and asleep, and between our thoughts. We have the ability when investigating a thought to go back to the point before the thought arose and rest there. Here awareness is as spacious as the night sky and the thought takes up the space of the moon. When looking into our own minds, all we can see is the thought because it is so bright. We ignore the rest. The "rest" we ignore is bodhi, pure mind. And although we dip into it constantly in this off-on manner, we leave its vastness completely unexplored. The "not two" means to enter it completely. Want to go exploring?
