I find the easiest, most subtle way to divine things is with the power of a good-old-fashioned candle or incense. I like to do this before prayer/spellwork etc. to give me a hint as to has it will go or how it went. Here are the meanings of different flame/smoke patterns:
Tall, strong flame: A good omen; your spell will thrive.
Regular flame: spell is proceeding as planned.
Dancing flame: A wild ride is ahead!
Sputtering flame: Your spell is faltering.
Refuses to light: May want to reconsider performing this specific spell or working.
Up: The energy is clear; a good omen.
North: You have gained the wisdom/experience you needed.
South: Change is on its way; focus on loving yourself.
East: Energy has been cleared/moved through.
West: Emotional purification or transformation is needed.
Now you know what your candle/incense may be trying to tell you! Happy divining, and may the blessings of Olympus fall gently on thy head.
