Equanimity, which every single religion of the word adores and promote is the state of being in the mental peace whatever be the situation. It is a state of having a calm, composed and neutral mind that does not get disturbed by emotions, pain and situations.
You can judge a person like this as a dry neutral or self-centred cold-hearted being. That is the ego’s judgement of atypical person. Buddha says that a mind filled with equanimity is” abundant, exalted, immeasurable, without hostility and without ill-will.”
Extroverted world value suffering more than peace. It expects emphatic behaviour towards the sufferer. It criticises the mind of equipoised as cruel, as having the heart of a stone. It judges a person who is not affected by overpowering emotional strains as ego. If you put this under the microscope you will understand the ignorance of the ego driven mind.
You always own the option of having no opinion.
