The word 'sin' is beautiful; it comes from a root which means 'forgetfulness'. You may not be able to see the connection between forgetfulness and sin, but there IS a connection: forgetfulness means unawareness, unconsciousness.
RajneeshMeditation, witnessing, silently sitting and looking at the mind, will be of much help. Not forcing, simply sitting and looking. Not doing much, just watching as one watches birds flying in the sky. Just Lying down on the ground and watching, nothing to do, indifferent. Not your concern really, where they are going; they are going on their own.
