Floating Wood
Meditate for half an hour.
Fill a clear glass bowl with fresh water. Drop a toothpick or other small wooden object into the middle of the dish. Since there will be no friction between the water and the object, it will be easily to move it because there is less resistance.
Get comfortable and breathe deeply.
Look at the toothpick. Imagine your mind's "hand" coming out and pushing on the object, and imagine it gliding across the water to the other side of the dish. Feel the energy pushing on it. You should begin to notice some movement after a while. You can use your hands to direct your energy, but don't touch or blow on the toothpick.
Once you have practiced this and you believe you have gotten the hang of it, take it one step further. Imagine that you are pushing down on the object, forcing it to go under the surface of the water. This will take more concentration, but the results are also more significant.
