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!
A nation which does not remember what it was yesterday, does not know what it is today, nor what it is trying to do. We are trying to do a futile thing if we do not know where we came from or what we have been about.
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.
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.
The body loaded by the excess of yesterday, depresses the mind also, and fixes to the ground this particle of divine breath.
[Lat., Quin corpus onustum
Hesternis vitiis, animum quoque praegravat una
Atque affigit humo divinae particulam aurae.]
[T]omorrow is a new day. You shall begin it well & serenely, & with too high a spirit to be cumbered with your old nonsense. This day ... is too dear with its hopes & invitations to waste a moment on the rotten yesterdays.
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.
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.
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.
