The lecture 'Vedanta Philosophy' was delivered by Swamiji on March 25, 1896 at the Graduate Philosophical Society of Harvard University.  The booklet also includes the questions and answers at two afternoon sessions with some Harvard students.  A few selections from Swamiji's other lectures have also been included in this booklet.  Some of the answers and selections cover the same general ground but they have all been retained on account of the variety in treatment.  Originally compiled and published in America by Mr. J.P. Fox.

This booklet presents the lecture 'Work and its secret' delivered at Los Angeles, California on January 4, 1900 plus a few other excerpts on Karma Yoga or yoga of action.
