When you are connected to the source, surrendered of ego and simply listening, you can send out a thought to someone in need, and it seems to make a difference sometimes. But you can’t force the hand of God. It doesn’t work that way.
All you can do is share your share of the divine presence with other beings where they are, and sometimes that’s enough.
I’m sure there’s much more that’s possible than just this. YThe same state we have in meditation has been used for millennia by shamans to lead their hunters to an animal pack; in their altered state they know that there is no space or time between them and the pack their hungry tribe are searching for.
Suffice to say that prayer with words is a slightly misguided use of time. When the disciples asked Jesus ‘how should we pray’, he gave the shortest answer possible – and half of it was about God’s will being done.
