This is the strongest prayer for Peace, after all everyone needs Peace now.
Raise your hands up and looking at the sky (if the Sun is visible, it is even better), read a prayer for Peace:
«Peace to the World. Hurrah.
I read a prayer
And direct Peace to the World.
May Peace reign on Mother Earth. May the Great Heavens and the Sun, our Luminary, hear my voice. Verily!»
Read it 9 times.
It is important to understand that religious prayers worsen the situation and bring it to a critical point. As a religious god is the one who is strong in battle. By strengthening it with a prayer for Peace or any other you increase the number of victims.
