Difference between prayer, meditation and magick

[anagogy]

Where do you see the difference?

Prayer
Essentially I see this as the process of supplicating another being, entity, or intelligence for assistance or information.

Meditation
I would say this is the process whereby one attempts to 'listen to the sacred silence' to become more aware of the truth of things beyond distortions.

Magick
I would describe magick as the process of utilizing the will to generate deliberate changes in reality/experience. One might define visualization as a kind of meditation but for me it falls under the rubrik of magickal work.
