There can be no deep disappointment where there is not deep love. – Martin Luther King, Jr.

The fact is that love is of two kinds, one which commands, and one which obeys. The two are quite distinct, and the passion to which the one gives rise is not the passion of the other. – Honore de Balzac

For one human being to love another that is perhaps the most difficult of all our tasks, the ultimate, the last test and proof, the work for which all other work is but preparation. – Rainer Maria Rilke
