One of the pillars of peace is truth. This means to say the truth, live in in your life with its consequences.
One other pillar is justice, that which implies doing what is just and to say what is honest even thouth it may cost us much.
The greatest of all the pillars is love. It is when we learn to love as God loves us. But you cannot also lack freedom, gift that makes us free to love and to respect, to be better to give our life the direction we may choose.
Do not forget: truth, justice, love and freedom are gifts of God for us to use each day. Good training!
With care and prayers,
your brother,
