My boss has childish temper tantrums and goes on the path of destruction. His anger and criticism was prodding me until I felt anger and a strong sense of self arise in me. I didn't know what to do because I was mainly practicing various forms of loving kindness meditation, and it didn't matter how peaceful and loving I could make myself with this type of meditation because clinging would arise in me, a sense of an angry I, and my peace would be destroyed.
I didn't know how to handle this situation and I still find myself caught in the same delusion, but have figured out how to pull myself out of it fairly quickly and let go of clinging to it.
An insight came to me in meditation: Ignorance is the only enemy. You don't get angry at an ant for being ignorant, so why get angry at anyone for being ignorant? In ultimate reality there is no self attacking another self. There is only ignorance attacking ignorance.
The way I've transcended above my boss's attacks is be constantly reminding myself of no self and that ignorance is the only enemy. When I see it this way, Right View has won the day and anger can't arise in me because the basis of anger has been wiped out.
