When someone is angry or doing something against us either we get angry or become upset, because it is very difficult for us to detach from what is happening outside. Therefore, we also participate by being emotional becoming Non-Divine.
How to help yourself in detaching from all that is not Divine?
Sri Aurobindo
Bring in Mother’s force to eliminate (your reaction).
Naran
There is a flower “IPOMEA CAIRICA”, which is light rose purple in colour….identified by The Divine Mother for detachment from all that is not divine.
Meditate on the flower praying, “Let Divine Love, Divine Life possess me, conquer me and keep me in lasting eternal immortal light”.
