The water you touch in a river is the last of that which has passed, and the first of that which is coming. Thus it is with time present. Life, if well spent, is long.

Amid the vastness of the things among which we live, the existence of nothingness holds the first place; its function extends over all things that have no existence, and its essence, as regards time, lies precisely between the past and the future, and has nothing in the present.

There's no other time but the present. Anything else is a waste of time.

Time stays long enough for anyone who will use it.

O Time, thou that consumest all things! O envious age, whereby all things are consumed!

O time, swift robber of all created things, how many kings, how many nations hast thou undone, and how many changes of states and of various events have happened since the wondrous forms of this fish perished here in this cavernous and winding recess. Now destroyed by time thou liest patiently in this confined space with bones stripped and bare; serving as a support and prop for the superimposed mountain.
