In the fully developed plant this rhythm repeats itself three times in succession and at ever higher levels, so that the plant, in climbing from stage to stage, each time goes through a process of withdrawal before appearing at the next. The greater the creative power required at a certain stage, the more nearly complete must be the withdrawal from outer appearance. This is why the most extreme withdrawal of the plant into the state of being takes place in the seed, when the plant prepares itself for its transition from one generation to another. Even earlier, the flower stands towards the leaves as something like a new generation springing from the small organ of the calyx, as does the fruit to the flower when it arises from the tiny organs of reproduction. In the end, however, nothing appears outwardly so unlike the actual plant as the little seed which, at the expense of all appearance, has the power to renew the whole cycle.
