We're all nothing but unified arrangements of atoms and particles, drifting around, enjoying consciousness every now and then for a second or so before splitting up to become bits and pieces of trees and stars and french fries.
A diamond cannot be polished without friction, nor a person perfected without trials. Someone is enjoying shade today because someone planted a tree a long time ago.
A sapling must be hedged about for protection, but when it becomes a tree, a hedge would be a hindrance. So there is no need to criticise and condemn the old forms.
A wild boar was sharpening his tusks upon the trunk of a tree in the forest when a fox came by and asked, Why are you doing that, pray? The huntsmen are not out today and there are no other dangers at hand that I can see. True, my friend, replied the Boar, but the instant my life is in danger, I shall need to use my tusks. There will be no time to sharpen them then.
