Levitating Things Using Wind

First of all Get into a meditative state while sitting down somewhere with wind flowing around your position (preferably outside). Now while sitting feel the wind, each gust and separate current, feel the wind brush and move past you. Now imagine altering the gusts and currents by making them blow harder or faster etc. then once you are in a meditative state, chant:

"By the Spirits of air.
I wish to bare a gale of air,
one strong enough to,
make ships sail
one strong enough to
make brick walls fail.
So that I may make things float.
So mote it be."

Then repeat it again as many times as you want.
