I do not think it is a matter of putting your anger aside. Instead, it is a matter of going ahead with forgiveness, if you so choose, even when angry. I say this because our science shows that as people forgive, their anger tends to lessen. So, you might want to start the pathway of forgiving even when you are angry. The process may help you reduce anger. In other words, you do not have to wait until the anger lessens before you start to forgive.
