The present moment

From Charlotte Joko Beck, Everyday Zen.

Buddha-nature requires that we... completely be each moment, so that whatever activity we are engaged in—whether we're looking for a lost sheep, or waiting for a friend, or meditating—we are standing right here, right now, doing nothing at all.

From S.N. Goenka, The Art of Living

Yet surely this moment, now, is the most important for us. We cannot live in the past; it is gone. Nor can we live in the future; it is forever beyond our grasp. We can live only in the present. If we are unaware of our present actions, we are condemned to repeating the mistakes of the past and can never succeed in attaining our dreams for the future. But if we can develop the ability to be aware of the present moment, we can use the past as a guide for ordering our actions in the future, so that we may attain our goal.

Although I agree, my question is whether these writers were living in the present moment as they were writing these words.
