The word ‘Om’ means simply accepting the life without expecting. There are three options for any situation in life either you can accept it or change it or leave it. You will be miserable and resentful if you do not take one these decisions.
Like if you can change it and choose not to change it or if you can accept it but choose to not to accept it or if you can leave it but choose not to leave it , then you are entering into the domain of disappointment, frustration and anxiety.
