What is a prayer? Prayer is a Point. It starts from a Point, which is the being, and doesn’t need time because it is already There.
True prayer is timeless, it is simultaneously throughout the universe in all conscious beings.
Even that being who is slightly more evolved than a monkey – who for the first time becomes aware of the Sun, sends a prayer to it and paints it on a rock – is contemporary to me and you in all the future existence.
Their prayer is contemporary to mine, and so are all the prayers of all sentient beings – apparently said in time.
If I pray now, I am together with that other being who will live on the Earth in a million years, just as I am together with the one who first looked at the Sun and became aware of being a conscious entity.
