NOW is thy reality in which time is contained. It is more and greater than time; it is an ever-present reality. It knows neither past nor future, and is eternally potent and substantial.
Every minute, every day, every year is a dream as soon as it has passed, and exists only as an imperfect and unsubstantial picture in the memory, if it be not entirely obliterated. Past and future are dreams; now is a reality. All things are now; all power, all possibility, all action is now. Not to act and accomplish now is not to act and accomplish at all. To live in thoughts of what you might have done, or in dreams of what you mean to do, this is folly: but to put away regret, to anchor anticipation, and to do and to work now, this is wisdom.
Whilst a man is dwelling upon the past or future he is missing the present; he is forgetting to live now. All things are possible now, and only now. Without wisdom to guide him, and mistaking the unreal for the real, a man says, “If I had done so and so last week, last month, or last year, it would have been better with me to-day”; or, “I know what is best to be done, and I will do it to-morrow.”
The selfish cannot comprehend the vast importance and value of the present, and fail to see it as the substantial reality of which past and future are the empty reflections. It may truly be said that past and future do not exist except as negative shadows, and to live in them — that is, in the regretful and selfish contemplation of them— is to miss the reality in life.
This is a beautiful essay from the great James Allen taken from the book All These Things Added
