The most advisable thing for the believer of God is to first make his own conception of God. Naturally man cannot make a conception of something he does not know. For instance, if I told you to imagine a bird that you have never seen, which is unlike any bird you have ever seen, you would first attach to the bird wings, then you might see the head of a cow, and then perhaps you would imagine the feet of a horse and a peacock's tail. But you cannot imagine any form which you have not seen, which you have not known. You have to embody from your mind a form which you already know. You cannot make a conception which you have never seen or known before. Besides, it is the easiest thing and it is the most natural thing for man to conceive of any being in his own form.
