Don't get angry (Okoru-na)*

1) Repeating "Just for today" helps stay in the present moment. Great creative power is found in the "now"present moment and it also makes the thought of not getting angry a lot more easier if it's just for today.
2) Principle #1 helps the root chakra.
When feeling anger, feel the feeling, give it space and find the cause of it as quickly as possible.
When we understand why we are angry, the energy of anger can be turned into a meaningful action.
