In Sufi terms the crushing of the ego is called Nafs Kushi. And how do we crush it? We crush it by sometimes taking ourselves to task. When the self says, 'O no, I must not be treated like this,' then we say, 'What does it matter?' When the self says, 'He ought to have done this, she ought to have said that,' we say, 'What does it matter, either this way or that way? Every person is what he is; you cannot change him, but you can change yourself.' That is the crushing. ... It is only in this way that we can crush our ego.
Hazrat Inayat KhanPeople in the world wish to make things rigid, things which are of the finest nature which words cannot explain. When a person describes the hereafter, it is just like wanting to weigh the soul or photograph the spirit. I personally think that you must be able to realize yourself what the hereafter is. You must not depend upon my words.
Hazrat Inayat KhanThe more one studies the harmony of music, and then studies human nature, how people agree and how they disagree, how there is attraction and repulsion, the more one will see that it is all music.
