I have read and truely believe it is very important to protect yourself before you try (and succeed with) an OBE. I usually say a prayer to God then ask to be surrounded and protected by His white light. While I'm visualizing this white light completely surrounding me like a heavy fog, I state that "In this light there is Divine protection and only God and good can penetrate this light".
What other means of protection do people do before an OBE?
Thanks
