A meditation tool upon the Magicians altar is the athame. One should meditate on the dagger. From a a place of the unconscious mind. The will and intellect. You must become the dagger. A symbol of power and fear. In ritual the tool is used to banish negativity in order to create a harmonious environment. When you meditate as the athame. Attempt to cut through all illusion upon the desired area of resolve. And to identify any uncertainty or weakness. About the problem in question. Whether that be a person including yourself. Or even the intentions of others.
