Falling in love is a big internal formation. Once you are in love, you think only of the other person. You are not free anymore. You cannot do anything; you cannot study, you cannot work, you cannot enjoy the sunshine or the beauty of nature around you. You can think only of the object of your love. That is why we speak about it as a kind of accident, “falling in love.” You fall down. You are not stable anymore because you have gotten into an accident. So love can also be an internal knot.
