Swami VivekanandaA man ought to live in this world like a lotus leaf, which grows in water but is never moistened by water; so a man ought to live in the world - his heart to God and his hands to work.
Swami VivekanandaMan stands in materialism; you and I are materialists. Our talking about God and Spirit is good; but it is simply the vogue in our society to talk thus: we have learnt it parrot-like and repeat it. So we have to take ourselves where we are as materialists, and must take the help of matter and go on slowly until we become real spiritualists, and feel ourselves spirits, understand the spirit, and find that this world which we call the infinite is but a gross external form of that world which is behind.
