Is it prayers of similar wording that pool together in the Collective Unconscious, or prayers of similar intention?

The effect of the collective unconscious flows from the energy of the intention, the information contained by the words of the originator, not by the words themselves. In this way, all thoughts from all people regardless of nationality and language of origin will find a resting place in a kind of complex hierarchical organization according to the intention of the originator. And it is those intentions that constitute the search criteria when new thoughts emanate from a person and impinge on the collective unconscious. It is the information content that finds its way to prior creations of thought and then may become amplified by reawakening or gathering together prior thought communications with a similar intention, and the resonance will echo back to the new thinker as a kind of reward to let them know they are on the right track in some way and are being mirrored by other people. So this is much like getting a pat on the back, a sense of reassurance they are not alone but are onto something and will likely find acceptance for their ways of thinking. So even thought done in isolation and not expressed on the spot to someone present has an audience, in a sense, and this helps the person with their growth, solely from this internal dialogue that comes via the collective consciousness of humanity echoing again and again among its participants.
