Anything that is secret and mysterious in this system of Yoga should be at once rejected. The best guide in life is strength. In spirituality, as in all other matters, discard everything that weakens you. Have nothing to do with it. Mystery-mongering weakens the human brain. It has well-nigh destroyed Yoga, one of the grandest of sciences
Swami VivekanandaWherever there is evil and wherever there is ignorance and want of knowledge, I have found out by experience that all evil comes, as our scriptures say, relying upon differences, and that all good comes from faith in equality, in the underlying sameness and oneness of things. This is the great Vedantic ideal.
Swami VivekanandaToo early religious advancement of the Hindus and that superfineness in everything which made them cling to higher alternatives, have reduced them to what they are. The Hindus have to learn a little bit of materialism from the West and teach them a little bit of spirituality.
