Furthermore, it sometimes happens that on sleeping for ten minutes you are subject to a year's-worth of different states. And even, if the words spoken and heard during a dream lasting one minute were collected together, for them to be spoken and heard in the waking world, a day or even longer, would be necessary. That means a single period of time is relative; it may seem like one day to one person and like a year to another.
Consider the meaning of this by means of a comparison. Let us imagine a clock which measures the speed of the movement displayed by man, cannon-balls, sound, light, electricity, spirit, and imagination. The clock has ten hands. One shows the hours while another counts the minutes in a sphere sixty times greater. Another hand counts the seconds in a sphere sixty times greater than the previous one, and yet others each count regularly decreasing fractions to a tenth of a second in vast spheres that regularly increase sixty times.
Let us suppose the circles described by the hand counting hours was the size of our clock, so that of the hand counting tenths of a second would have to be the size of the annual orbit of the earth, or even larger. Now, let us suppose there are two people. One of them is as though mounted on the hour-hand and observes according to its motion while the other is on the hand counting tenths of a second. There will be an enormous difference, as great as the relation between our clock and the annual orbit of the earth, as regards the things observed by these two individuals in the same period of time.
Thus, since time is like a hue, shade, or ribbon of motion, a rule that is in force in motion is also in force in time. And so, although the things we observe in the period of one hour would be equalled in amount by the conscious individual mounted on the hour-hand of the clock, like the one mounted on the hand counting tenths of a second, God's Noble Messenger (Peace and blessings be upon him) mounted Buraq of Divine Assistance and in the same space of time, in that specified hour, like lightning traversed the entire sphere of contingency, saw the wonders of the outer aspects of things and the aspects which look to their Creator, ascended to the point of the sphere of necessity, was honoured with Divine conversation and favoured with the vision of Divine beauty, received his decree, and returned to his duty. It was possible for this to happen, and it did happen.
