1. The first secret is the secret of form--that every form has been built up on a perpendicular and a horizontal line. Fruit, flower, leaf, in everything one can see the cross as its basis. It becomes fully manifest in the form of man, this being the perfect form. It is perfect because every form of the mineral, vegetable, or animal kingdom has evolved gradually and developed in the human form. One can notice this by studying the indistinct human form even in the mineral and vegetable kingdoms. Not only the animals have a resemblance to man's form and face, but even in the rose you can see man's face indistinctly. In the pebbles by the seashore, in the rocks, in mountains, one sees an indistinct human form. And when one distinguishes the human form in its real aspect, it is nothing but a cross.
