A soup kitchen is read as need and generosity together. Serving in one stands for the wish to help; waiting in line, for a hunger — emotional more often than material — that asks to be met.

My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
