Superstitions are all materialism, because they are all based on the consciousness of body, body, body. No spirit there. Spirit has no superstitions - it is beyond the vain desires of the body.
Swami VivekanandaNature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies. But the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
Swami Vivekananda
