I could not have left this one! Homeopathy does consider that we all have a ‘spirit like’ vital force, which animates us. And it is this spirit like vital force which gets deranged before we fall sick. Also most of the humanity believes in God. And if you believe in God, you cannot logically disbelieve the spirit within us. And since homeopaths themselves are human beings and deal with other human beings, we cannot just shun the beliefs of a large proportion of humanity. We need to work with them and on them.
You’ve probably come across all kinds of cleansing and detox programs online. There is a whole industry based around selling these plans and supplies to people trying to live healthier.
