Advaita Vedanta has to be cleared of the incrustation of scholasticism. - Swami Vivekananda

I have always found “Occultism” injurious and weakening to humanity. What we want is strength. We Indians, more than any other race, want strong and vigorous thought. We have enough of the superfine in all concerns.

For centuries we have been stuffed with the mysterious, the result is that our intellectual and spiritual digestion is almost hopelessly impaired, and the race has been dragged down to the depths of hopeless imbecility never before or since experienced by any other civilized community.

There must be freshness and vigour of thought behind to make a virile race. More than enough to strengthen the whole world exists in the “Upanishads.” The Advaita is the eternal mine of strength*—but it requires to be “applied.” It must first be cleared of the incrustation of scholasticism,* and then in all its simplicity, beauty, and sublimity be taught over the length and breadth of the land, as applied even to the minutest detail of daily life.

This is a very large order, but we must work towards it, nevertheless, as if it would be accomplished tomorrow. Of one thing I am sure that whoever wants to help his fellow beings through genuine love and unselfishness will work wonders.
