This question while dealing with what earth-men call time does not, of course, touch the real meaning of time itself, that is, of what may be in fact for this solar system the ultimate order, precedence, succession, and length of moments. It is a question which may be answered in respect to our time, but not certainly in respect to the time on the planet Mercury, for instance, where time is not the same as ours, nor, indeed, in respect to time as conceived by the soul. As to the latter any man can see that after many years have slipped away he has no direct perception of the time just passed, but is able only to pick out some of the incidents which marked its passage, and as to some poignant or happy instants or hours he seems to feel them as but of yesterday. And thus it is for the being in _devachan_. No time is there. The soul has all the benefit of what goes on within itself in that state, but it indulges in no speculations as to the lapse of moments; all is made up of events, while all the time the solar orb is marking off the years for us on the earth plane. This cannot be regarded as an impossibility if we will remember how, as is well known in life, events, pictures, thoughts, argument, introspective feeling will all sweep over us in perfect detail in an instant, or, as is known of those who have been drowning, the events of a whole life time pass in a flash before the eye of the mind. But the Ego remains as said in _devachan_ for a time exactly proportioned to the psychic impulses generated during life. Now this being a matter which deals with the mathematics of the soul, no one but a Master can tell what the time would be for the average man of this century in every land. Hence we have to depend on the Masters of wisdom for that average, as it must be based upon a calculation. They have said, as is well put by Mr. A. P. Sinnett in his _Esoteric Buddhism_, that the period is fifteen hundred years in general. From a reading of his book, which was made up from letters from the Masters, it is to be inferred he desires it to be understood that the devachanic period is in each and every case fifteen centuries; but to do away with that misapprehension his informants wrote at a later date that that is the average period and not a fixed one. Such must be the truth, for as we see that men differ in respect to the periods of time they remain in any state of mind in life due to the varying intensities of their thoughts, so it must be in _devachan_ where thought has a greater force though always due to the being who had the thoughts.
