…ever since their first descent at the time of the breaking of the vessels… For afterwards there was a further descent when the moon was made smaller, and Adam’s sin was also a descent.
…in order that they should ascend little by little until everything returns to the level of completeness as before the breakage. This follows the principle that everything must be gradual and in stages.
And now there are ascents and descents depending on the different times… In the meantime there are both ascents and descents. For as long as the worlds have not reached their highest possible level they can still ascend and descend. No level is permanently attained through a one-time ascent. Time factors play a large part in this. As long as the ascent to a given level is not permanent it is possible to rise to and fall from it time after time.
