Take all reasonable advantage of that which the present may offer you. It is the only time which is ours. Yesterday is buried forever, and to-morrow we may never see.
But our minds are bound to the yardstick of yesterday, today and tomorrow, and with that yardstick we try to inquire into the unknown, to measure that which is not measurable.
I have got this letter which actually goes out the day after I die. It has already been written. And it says that: "Yesterday I died". And then it says: "That's bad news for me, but it's not bad news for you, the shareholders of Berkshire". And then I go on and explain what is going to happen. I know that is one time when they will be really interested in hearing from me.
For you [God] are infinite and never change. In you "today" never comes to an end: and yet our "today" does come to an end in you, because time, as well as everything else, exists in you. If it did not, it would have no means of passing. And since your years never come to an end, for you they are simply "today."
What we are today comes from our thoughts of yesterday, and our present thoughts build our life of tomorrow: our life is the creation of our mind. If a man speaks or acts with an impure mind, suffering will follow him as the wheel of the cart follows the beast that draws the cart. If a man speaks or acts with a pure mind, joy follows him as his own shadow.
So yesterday you fell off the wagon? Or maybe you blew your diet? Or lost your temper and shot off your mouth? Well, that was yesterday. Today is a brand-new day with a clean slate, so forget yesterday!
With the mistake your life goes in reverse. Now you can see exactly what you did Wrong yesterday and wrong the day before And each mistake leads back to something worse.
To be free of all authority, of your own and that of another, is to die to everything of yesterday, so that your mind is always fresh, always young, innocent, full of vigour and passion. It is only in that state that one learns and observes. And for this, a great deal of awareness is required, actual awareness of what is going on inside yourself, without correcting it or telling it what it should or should not be, because the moment you correct it you have established another authority, a censor.
You have it now and that is all your whole life is; now. There is nothing else than now. There is neither yesterday, certainly, nor is there any tomorrow.
