Yet, the past can never be put aside. There is a watching of the past as it goes by, but not occupation with the past. So the mind is free to observe and not to choose. Where there is choice in this movement of the river of memory, there is occupation; and the moment the mind is occupied, it is caught in the past; and when the mind is occupied with the past, it is incapable of seeing something real, true, new, original, uncontaminated.
