578 Cf.
2:25 and n. 44. 579 The Garden is contrasted with the Fire: the shade is contrasted with the roasting. Evil grows with what it feeds on. So goodness and felicity grow with their practice. The good may be alone to start with, but (unlike evil ones) they get Holy Companions. Just as agony increases with what it suffers (typified by fresh skins growing as the old ones burn out), so felicity finds deeper and deeper meaning (typified by the shades in a garden, which grow deeper and cooler as you proceed into the interior), (Cf.
13:35 ).
