Hazrat Thanvi (may Allah Ta’ala have mercy on him) further used to say that the aim of treating bad moral values is not to get rid of them completely, as many of these are natural instincts and it is not possible to do so. The idea is to keep opposing them through one’s thoughts and behaviours so much that they become so weak as if they do not exist anymore. This process of enhancing and further developing good moral values, and weakening and attenuating bad moral values, is called Tazkiyah and this is the primary goal of Tasawwuf.
