We have previously written two articles on our understanding of the commandments regarding clean and unclean. We have since received some questions which we were very interested to find answers for. One of these questions are: How do we make sure we do not come into contact with anything or anyone who is unclean in order to make sure we don’t become unclean? We might, unknowingly, touch a person who is unclean or use public transport and sit on a chair where an unclean person sat. We might, for this reason, always be in an unclean state. The question is, does this really matter? Should we even pursue this?
