Great power is at hand. Use it for righteous purpose.
Read the text from Richard Wilhelm's translation of the I Ching
“Thunder – electrical energy – mounts upward in the spring. The direction of this movement is in harmony with that of the movement of heaven. It is therefore a movement in accord with heaven, producing great power. However, true greatness depends on being in harmony with what is right. Therefore in times of great power the superior man avoids doing anything that is not in harmony with the established order. ”
