Spiritual understanding centers on the acceptance of a divine truth, which gradually reveals itself, rising on the horizon of the mind till it pervades all. If the mind and its reactions are brought into willing obedience to that truth, the divine truth continues to permeate the mind even more and the mind develops with it endlessly... It is we who must yield to the love of God so that our minds may be open to the divine truth.
A joyful mind is very ordinary and relaxed... When your aspiration is to lighten up, you begin to have a sense of humor. Things just keep popping your serious state of mind. In addition to a sense of humor, a basic support for a joyful mind is curiosity, paying attention, taking an interest in the world around you... Noticing everything. Appreciate everything, including the ordinary. That's how to click in with JOYfulness.
