“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 yesterday, a week ago, a year, ten years ago, one can say unmistakably what will and what will not happen tomorrow.” (Gurdjieff)
