Basically, if the mind stays in the present, it's impossible to worry. Upon careful consideration, it becomes clear that human beings are capable of worrying only about an event that has already transpired or one that may take place in the future (although the occurrence might have just happened or may be about to happen in the next instant). The present moment contains no time or space for worry.

Nakamura Tempu Sensei viewed the mind as a segment of the body that could not be seen and the body as the element of the mind that was observable. He also likened the mind and body to a stream, with the mind as the source flowing down to the body. Whatever we drop in the stream will be carried down by the current. In like manner, our thoughts will influence the body and our well being.

By 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".

A strong life force can be seen in physical vitality, courage, competent judgment, self-mastery, sexual vigor, and the realization of each person's unique talents and purpose in life. To maintain a powerful life force, forget yourself, forget about living and dying, and bring your full attention into this moment.

The young should not think of themselves as immature and the elderly need not view themselves as feeble. Our minds control our bodies. Have no age, transcend both past and future, and enter into naka-ima-the "eternal present".

Realizing 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.

If we fail to realize our full potential as human beings, we live more on an animalistic level. This is fine for dogs, cats, and chimpanzees but doesn't work quite so well for women and men. Without the capacity to freely shape our own lives, much as a sculptor might carve stone, we inevitably slip into negativity and depression.
