In all art there are three stages, and especially in sculpture. The first stage is conception; the next stage is composition; and the third stage is production. If the artist is not capable of conceiving an idea, he cannot go any further. He may try hundreds of times, but he will not arrive at the desired result. The outer world may help to bring about such a conception, but it must actually spring from within. It depends upon the stage of the artist's evolution; according to his evolution he is able to catch, to sense, the rising stream of inspiration which comes from within.
