Jorge Luis Borges Seven Nights

We must reach the understanding that the world is an apparition, a dream; that life is a dream. But we must feel this deeply. In the Buddhist monasteries, the neophyte must live every moment of his life experiencing it fully. He must think: "Now it is noon; now I am crossing the patio; now I will meet the superior." And at the same time he must think that the noon, the patio, and the superior are unreal, that they are as unreal as he and his thoughts.

One of the great delusions is the I. There is no subject; what exists is a series of mental states. If I say "I think," I am committing an error, because I am assuming a fixed subject and then an act of that subject, which is thought. It is not so. One should say, not "I think," but rather "it is thought," as one says "it is raining." When we say "it is raining," we do not think that the rain is performing an act but rather that something is happening. In the same way that we say "it's hot," "it's cold," we should also say "it's thinking," "it's suffering," and avoid the subject."
