The three days of the full moon are each filled with a special energy, and any one of the three is appropriate for gathering--depending on what a group might want to do. Some practitioners of the Old Religion say the waxing first day of the full moon is for increase, the full second day is for reckoning (accounting) and the waning third day of the full moon is for clearing, and/or for sending wishes to manifest within the month of the next full moon...which would then be welcomed on the day of increase and "reckoned" on the full moon day and on and on.
Each of the four card suits in the Journey Oracle is associated with themes of meaning. The full moon cards carry the themes of Discipline and Trust. It takes discipline to honestly reckon the way in which our intentions and wishes have manifested across our month of daily experience, and certainly it takes trust to cast our desires like a shimmering net out to the next moon, hopefully to catch what we need more than what we want.
Discipline and trust are best not treated as conditional. Discipline lives at the core of responsibility. It means feeling what is required, and doing it, more than negotiating or interpreting what is known of that responsibility. Trust lives in the rarest atmosphere of all. The one that surrounds us when we feel that someone or something is depending on our actions. Trust relies on discipline like the tides need the full moon. Ultimately, the only question that really matters is this one that came in a dream for the Blue Moon card in the Journey Oracle.
