Time speeds up and slows down. I think it's true. The physicists tell us time bends; that it's a flexible dimension.
And we experience that flexibility too. Time will drag, or zip by in a flash. Sometimes meditating messes with time, it seems to to slow it down and speed it up simultaneously.
We are born into this time-realm. And the tempo of life seems to speed up as you get older. As Charles Bukowski once put it: "Days run away like wild horses over the hills."
When you were smaller, and your head was softer, the days could slow down and spread out like a welcoming bed of flowers.
Now that you are bigger, and your head is harder, the days speed up like a careening car out of control. Everything is blur and flash. And you hang on, and try to savor the moments as they zip by.
