Equanimity is the quality of being even-tempered and unaffected by outside influences. It does not mean that you are indifferent to what is happening around you; you just don’t allow it to upset your inner peace. Here’s a basic equanimity practice. Whenever you feel a strong emotion coming on – a response to pain or pleasure, success or failure, extreme stress or thorough relief – say to yourself, “This, too, will pass.”
