The Principal of Time
There is no process that does not require time.
All processes require time. For anything to be a process it must first have a beginning and an ending along with the procession of events which is the occurring. So to have all of these components together a period of time is required. This may be a really short period or a long period, either way there has been a lapse of time. This is true for most elements of life – in particular healing. If we were to cut our finger, for example, a period of time would lapse between the cutting and the full healing of that cut.
