Self-respect and a sense of superiority are two very different things. Self-respect is not necessarily a sign of egoism any more than its absence is a sign of liberation from egoism. Self-respect means observing a certain standard of conduct which is proper to the level of manhood to which I belong—e.g. I cannot make a false statement out of self-respect though it would be advantageous to do it and most people under the circumstances would make it. Amour-propre is different and belongs to the sattwic type of ego. When one is not free from ego, then amour-propre (as well as self-respect—for that can be with ego or without ego) are necessary supports for the maintenance of the personality at its proper level.
Hatred being very unspiritual is not an aid to be called in for the purpose.
