"Sages such as Sri Aurobindo who have meditated on Hindu iconography, and savants such as Ananda Coomara-swamy, Stella Kramrisch, and Alice Boner who have studied the subject, assure us that the forms and features of Hindu icons have a source higher than the normal reaches of the human mind. The icons are no photocopies of any human or animal forms as we find them in their physical frames. They are in fact crystallizations of the abstract into the concrete, of the infinite into the finite. They always point beyond themselves, and a contemplation of them always draws us from the outer to the inner. Hindu Šilpašãstras lay down not only technical formulas for carving holy icons in stone, and metal, and other materials. They also lay down elaborate rules about how the artist is to fast, and pray, and otherwise purify himself for long periods before he is permitted, if at all, to have a psychic image of the God or Goddess whom he wants to incarnate in a physical form. It is this sublime source of the Šilpašãstras which alone can explain a Sarnath Buddha, or a Chidambram Natarãja, or a Vidisha Varãha, to name only a few of the large assembly of divine images inhabiting the earth. It is because this sublime source is not accessible to modern sculptors that we have to be content with poor copies which look like parodies of the original marvels."
