After observation one will come to understand, "All I like in the world is what I have always liked, and all I dislike is what I have always disliked in life." It can be said in other words, "What I know to be loveable I have always loved and all that I don't know I cannot love at once." This shows that ignorance becomes a cover over all that is beautiful and ugly, and knowledge uncovers it; liking comes from knowledge and dislike from ignorance, although both are necessary. Also it is possible that through ignorance one may like a certain thing and by knowledge one may rise above that liking. However, the higher knowledge must always give liking for all things, and things which do not deserve liking, above them a soul will rise by the help of knowledge.
