As far as I'm concerned O'Sensei planted some seeds and those seeds grew into trees like Saotome and in turn he plants some seeds etc. Along comes some outside influence with some fertilizer and if it works those trees will flourish, if it doesn't then the trees of their own free will will change the fertilizer.
Meanwhile more trees grow and all is good.

Are sugar maples lessened by the existence of aspens?
