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.
And although our bodies are bounded with skin, and we can differentiate between outside and inside, they cannot exist except in a certain kind of natural environment.
One can see light above the head; that indicates a consciousness outside the body. But that itself is not the Truth-Consciousness or Vijnana. But much light descending from there illumines this consciousness.
