Why is it that during our most exalted and purest emotional happiness, such as that which comes from listening to fine music or looking at a landscape of wild grandeur or giving ourselves up to, mystical rapture, time seems to be blotted out and we remember its existence only when we are recalled to our ordinary prosaic state? Consider that this strange feeling never arises during our more worldly or more painful episodes. The explanation lies in mentalism. All human experience, including the physical, takes place in the mind. Each episode must be thought into consciousness before it can ever exist for us. If the episode is a happy one, we love to dwell on it, to linger in it, and to become absorbed by it. Such intense concentration greatly slows down the tempo of our thoughts and brings us nearer the utter thought-free stillness wherein our spiritual self forever dwells outside time and space.
This kind of experience demonstrates vividly to those who have not yet been able to practise the meditation required for, and leading up to mystical rapture, what mystics find during such rapture--that man in his true being, in his Overself, is not only timeless but also sorrowless.
