All that people want to create is something of beauty. Something perfect, immaculate, pristine, pure. And they succeed too, if most of them, in the end do beget a child, thats exactly what they have created. But the child also inherits the imperfections and failings and genetic predispositions towards improper tendencies. And over and above that, the parents also fail, almost always, to give perfect upbringing to their kids and they turn then, less than perfect.
Its an infinite cycle that we repeat. Have repeated, will do, ad infinitum.
Those who deviate from this way of creating beauty. Those who dedicate themselves to some other pursuit, their work, their passion, their bodies, anything other than focusing on the whole plan to create beauty through reproduction, also end up creating things which might be perfect and pure and beautiful in the beginning, but which deteriorate and degrade deform and become totally different than what they started off of as.
In this, we have to understand, is the basic fact. The act of creation is not supreme in itself or the final one. Its the act of maintenance that goes a long way in keeping things in order. Its not as much as cleaning your room but keeping your room clean. Because we all are fighting against attrition by entropy and in this battle, creating things of beauty is not enough. You have to invest energy in it even after the creation in form of fixing it and keeping it in its form.
