While we can learn or study techniques for almost anything we might want to accomplish, real understanding is not the mere accumulation of knowledge. Understanding cannot be realized by listening or reading about the realization of others. It must be achieved firsthand via substantive, direct perception in the moment.
H. E DaveyRealizing that our minds control our bodies while our bodies reflect our minds amounts to understanding the most fundamental aspects of ourselves. It further equals a comprehension of the relationship between our "tools." And since the mind and body are interrelated, this understanding makes it easier to see why coordinating them is a practical way of using these tools to greatest effect-a way of using the mind and body to live our lives as art.
H. E DaveyOur past cannot be changed, and to be preoccupied with it is inefficient in time and effort. Likewise, by fretting over the future, we only exhaust ourselves, making us less able to effectively respond when the future is actually upon us. By worrying about a mishap that may or may not take place, we're forced to undergo the event twice-once when imagining it and once again if and when we actually experience it.
H. E DaveyBy keeping the mind in the present, unless you deliberately want to contemplate the past or future, it's possible to firmly face life without fear. Then, no thoughts of past failures or future problems will exist in the mind, and a truly positive mental state will result-fudoshin, the "immovable mind".
H. E DaveyUsing the combined, integrated force of the mind and body is more efficient than using one without the other. Since the body can only exist in the present, that's where the mind should be too (unless we deliberately choose to contemplate the past or future). At the same time, the body needs to be healthy and in optimum operating condition so that it can respond effectively to the mind's directives.
