an excerpt from In search of the miraculous By P. D. Ouspensky, Marianne Williamson
In order to know the future it is necessary first to know the present in all its details, as well as to know the past. Today is what it is because yesterday was what it was. And if today is like yesterday, tomorrow will be like today. if you want tomorrow to be different, you must make today different. if today is simply a consequence of yesterday, tomorrow will be a consequence of today in exactly the same way. And if one has studied thoroughly what happened yesterday, the day before, a week ago, a year, ten years ago, one can say unmistakably what will and what will not happen tomorrow. What happens or may happen to us may depend upon three causes : upon accident, upon fate, or upon our own will. Such as we are, we are almost wholly dependent upon accident. We can have no fate in the real sense of the word any more than we can have will. If we had will, then through this alone we should know the future, because we should then make our future, and make it such as we want it to be. If we had fate, we could also know the future, because fate corresponds to type. If the type is known, then its fate can be known, tat is, both past and the future. Today a man is one, tomorrow he is different : today one thing happens to him, tomorrow another.
