Blind acceptance of everything infers an allowance of anyone to do anything, both in the world and to us. Why would we simply accept that someone is violent to us, for example? I feel this comes down to the definitions being used in the concept of 'acceptance'. We do need to have acceptance of the existence of what is, in order to not deny reality - however, we do not need to accept everything that exists has a 'right' to be in our reality. 'negative' is the mother of change and as long as we deny our real feelings that some things must be changed for balance to manifest, we will find true joy and success elusive.
