10. Spiritism makes the act of prayer understandable by explaining how thought is transmitted, either when the Spirit to whom we are praying comes to our help, or when our thoughts raise themselves up to this being. In order to understand what happens in this circumstance, it is necessary to consider all incarnate and discarnate beings as immersed in the Universal Cosmic Fluid which occupies space, as we on Earth are immersed in the atmosphere. This fluid receives an impulse from will-power, which is the vehicle of thought just as air is the vehicle for sound, with the difference that the vibrations of air are circumscribed, whereas those of the Universal Cosmic Fluid extend infinitely.
So when a thought is directed at someone either on Earth or in space, from an incarnate to a discarnate being, or vice-versa, a fluidic current is established between them which transmits the thought from one to the other, just as air transmits sound.
The energy contained in this current remains proportional to the force behind the thought and the desire. This is how the Spirits hear the prayers directed to them wherever they may be. It is also how Spirits communicate amongst themselves, how they transmit their inspirations to us and how contacts are established at a distance between incarnates.
This explanation has in mind especially those who do not understand the utility of completely mystical prayer. It is not meant to seemingly materialise prayer, but rather to make its effect intelligible by showing it can have direct and effective results. But this does not make it any the less subordinate to God's wishes; He being the Supreme Judge of all things, it is only through His wishes that the action of prayer may become effective.
