Clarity

Place a bowl of water on your altar, and light some Herbal incense. (Rosemary is good, or sage)

Light a white candle and place is so that the flame is reflected in the water in your bowl.

Clear your mind and watch the flickering flame, and feel the air blowing away the cobwebs in your mind... and say:

"Powers of the air
Gentle and fair.
Send me your sight
for clearness of sight"

Feel your mind clearing the clutter and dust bunnies out.

Focus on what you want to know.. or remember where you put something... 

let your mind become clear and focused... then blow the candle out, and take a sip of the water in your bowl.
