We are either in the state of “having lived” or “will be living” — that’s how our mind functions. Often, our mind is dwelling in the past and we are always “sort of living” in the state of past memories. Our mind has never been free to live in the present: it’s always under the dictatorship of our memories of the past or dreams of the future. We have a long list of plans for how we will live in the future — how we will achieve this and that — and we invest our energy, time and effort in these dreams. As a result, we may actually achieve a certain number of our dreams, but when the future becomes the present, we don’t have the time or wisdom to experience it. We don’t have the space, the freedom, to enjoy the dreams that have come true in the present.
The whole purpose of mindfulness of mind is to bring us back to this tiny spot of the present, the momentary nature of our mind, and to experience the infinite space and freedom within that speck of existence. In order to do that, we must experience the lively nature of our mind, which is so present, so momentary and so fresh. Every individual moment, every individual fragment of that mind, is completely pure and fresh in its own state. The whole point is to experience this freshness and genuineness — the honest face of that tiny spot — without coloring it with our memories, concepts, philosophies or expectations. Experiencing it without all these is what we call simply being there.
