This translation captures the meaning and beauty of the twelve principal Upanishads, omitting a few passages. Original text is not given. An excellent version for the general reader.
Love is always mutual and reflective. You may hate me, and if I want to love you, you repulse me. But if I persist, in a month or a year you are bound to love me. It is a well-known psychological phenomenon.
-Swami Vivekananda
