If it is something which is not in any relation to all things known, such existence can not be established by any reasoning. How do we know that something, which is not associated with other things, exists at all? The whole universe, such as we know it, is a system of relationships; we do not know anything that could not be related. How can that, which is not dependent on anything and not related to anything, form items related to each other and dependent on each other in its existence?
Is either unity or multiplicity. If there is one, how it can cause a variety of things that come from different causes? If they are as many as there are things, how can the latter be related to each other? If it permeates everything and fills the entire space, it can not create them, because there would be nothing to be created.
If deprived of all properties; all the things that arise, should also be free of all properties. So it can not be their cause. If it is different from the properties, how it still creates things having these properties and manifests itself in them?
If it is invariable, all this should also be invariable, as a result can not vary in its nature with the cause. But all the things of the world are subject to changes and decomposition. How, how can it therefore be invariable?
If created the world, there would be no changes or destruction, there should also be no sorrow or unhappiness, right and wrong, given that anything both pure and impure, would have to come from somewhere. If sadness and joy, love and hatred arise in all sentient beings, then he should be able to feel sadness and joy, love and hate, and if it has this ability, how can we say that it is perfect?
If it was the creator, and all beings would have to be its silent followers, how would it be useful to practice virtue? If all deeds are its formation, they must be the same as their perpetrator’s. But if grief and suffering is attributed to another cause, in that case there is something that it is not the cause of. Why, then, would not be without a cause all that there is?
If there is the creator, it works with some purpose or no purpose. If it works with some purpose, you can not say that it is perfect, because the purpose necessarily implies satisfying a want. If it works without the purpose, it is similar to a madman or an infant.
