Meta. Every state of consciousness is formed by groups of ideas. Some dominant idea is the nucleus, and about this the ego builds a mental house. Thus are reared walls, or ideas of separation, that shut out the universal light, and the ego finds itself a prisoner in a dungeon of its own construction.
These mental houses are impregnable to light when there is a belief that the light does not shine. This darkness shuts them away from other groups of ideas, or states of consciousness, that would gladly reflect light into them. Abraham said to the rich man in torment, "Between us and you there is a great gulf fixed, that they that would pass from hence to you may not be able, and that none may cross over from thence to us." Then the rich man requested Abraham to send Lazarus to tell his brethren what the ideas they were cultivating would bring them to; but recognizing that they were in still another state of consciousness, a consciousness impregnable to ideas not of its order, Abraham told him that they would not heed even "if one rise from the dead."
