It seems to me that peace is not just the absence of violence, but something much more. The world is closely connected with our inner attitude, with motivation, with compassion. Any movement, any action that we perform out of compassion, in fact, carries the world in itself. And any action performed under the influence of negative emotions - hatred, anger, envy - in fact, is violence.

And one more explanation: the world is creation, emergence. We are all living beings, including trees and grasses. Plants are also alive. Although they do not have consciousness, due to their chemical and biological properties, they have the ability to be born and exist.
Therefore, when spring comes, trees and grass begin to flourish, when the sun rises, heralding a new beginning, we feel happiness.
Then autumn comes. Leaves change colour and eventually fall off. And now only bare trees remain. Compared to our spring moods, here we experience inner discomfort. Without water, flowers stand for several days, and then wither.
