2. Energy:
Despite what you may have read or been told about out of body travel, it is all about energy. The reason your consciousness is Earth bound is because you lack the fine and powerful energy necessary to free yourself of this plane. To achieve consistent out of body travel you must do some form of energy raising routine everyday. This can be some form of chakra exercise (as in the MPE - Middle Pillar Exercise), meditation (with or without crystals), prayer, or some other form of energy raising technique. (Wisdomsdoor)
