There is surely nothing other than the single purpose of the present moment. A man's whole life is a succession of moment after moment. If one fully understands the present moment, there will be nothing else to do, and nothing else to pursue. Live being true to the single purpose of the moment. Everyone lets the present moment slip by, then looks for it as though he thought it were somewhere else.
What doth care about future events bring thee, save sorrow upon sorrow? Sufficient for the day is the evil thereof. It is vain and useless to be disturbed or lifted up about future things which perhaps will never come.
Remember that man lives only in the present, in this fleeting instant; all the rest of his life is either past and gone, or not yet revealed. Short, therefore, is man's life, and narrow is the corner of the earth wherein he dwells.
What I urge is that you so learn to control the machinery as to live with 'day-tight compartments' as the most certain way to ensure safety on the voyage. Touch a button and hear, at every level of your life, the iron doors shutting out the dead yesterdays and the unborn to-morrows.
The miracle is not to walk on water. The miracle is to walk on the green earth in the present moment, to appreciate the peace and beauty that are available now.
