Greetings Ilikeseggs, and

for your wonderfully thoughtful addition here.
I now add...
There is a central fact that applies to all the above as well as much else besides:
Our species leans VERY heavily towards obsessing about things.
(This is often expressed as something else=> addiction, which is just the next step.)
Yes - thoughts have great power and are totally central to our lives.
Also, when we obsess around a single subject, that creates a powerful focus which can be trained to work correctly, as desired.
All the above lends credibility to LOA, deep meditation, devout prayer, etc., etc., etc...
Next, add in the possibility of a group with intense desire of a single goal like healing a single person who has been badly injured - and the results can look quite miraculous.
(Example - a nation-wide prayer vigil for a well-loved injured person.)
Our species is capable of truly great things if/when we aim ourselves away from the urges to harm and/or kill, and especially when minds can be brought into harmonious agreement.
There is a bible line that begins with 'when 2 or more are gathered...' that actually describes this phenomena.
Even though I am totally non-religious I willingly point to that as a truth regardless of whether it is in a diety's name, or not.
(Personally I prefer the wiccan rede's saying of: "An Ye Harm None, Do What Ye Will" )
