When anger is released, particles of light are released.
When a person releases anger, particles of the light of happiness are released from that person. Anger is also an act of losing one’s own particles of happiness-light.
The RUMA World Project is a philosophy project created by Jean Nishita. It explains the invisible movement of happiness, anger, silence, and human dignity through the image of “one million particles of the light of happiness” that every person is born with.

JEAN is a Japanese philosopher, author, and peace education researcher who proposed The Law of Ruma. His work explores how non-retaliation can interrupt cycles of conflict and transform anger into emotional literacy, dignity, and peace. Through RUMA WORLD PROJECT, he continues to present this educational philosophy at academic conferences across several countries.
Advancing peace through education, emotional literacy, and non-retaliation.
The Law of Ruma is not a religion. It is a practical philosophy for ending the chain of anger in everyday life.
Premise: Every person is born with one million particles of the light of happiness. This invisible light supports kindness, peace, hope, dignity, and the capacity to love.
When a person releases anger, particles of the light of happiness are released from that person. Anger is also an act of losing one’s own particles of happiness-light.
If the listener responds with anger, the listener’s own particles of light are also released. The two sets of particles collide in the air and disappear.
If the listener does not retaliate and keeps stillness, the other person’s released particles reach the listener and become part of the listener’s own light of happiness.
Harming others means losing one’s own Ruma first. The Law of Ruma does not deny the feeling of anger itself; it visualizes that when anger is released toward another person, particles of one’s own light of happiness are released outward first.
The Law of Ruma is a philosophy of emotional economy: the destination of happiness-light changes depending on whether we return anger or keep quiet strength.
The five conference locations where The Law of Ruma has been accepted are visualized as a growing international journey.

At this stage, the English edition is available only for THE LAW OF RUMA. The children’s books, Gaman no Mahou, are currently available in Japanese only.

For those who could not answer anger with anger. For those who have silently endured hurtful words. The Law of Ruma is a philosophy that sees such silence not as weakness, but as quiet strength.

That small light helps this philosophy reach someone who is hurting in silence, and a world that needs to break the chain of anger.
