especially if it is repeatable rather than a one off occurrence.
'Aye, there's the rub' as Shakespeare said. Remember that Tom Campbell spent decades reaching this point in his explorations. As Tom explains many times, NPMR exploration requires interpretation and many repetitions to figure out what is really going on. Most people are seeking 'thrills' and perhaps 'chills'. But if you are seeking confirmation of what Tom teaches, expect to put in decades of serious work.
This is why we sort of warn you away from this path unless you are seriously prepared for the long haul. There are plenty of other ways to realize that there is more to Reality and it is like Tom describes. Meditation is the key in any case. And it is also requisite for NPMR access whether OBE or any other kind of LCS contact. When you ask and receive answers from guides, will that not tell you something? That is one of the kinds of things that Tom explains that you can do. And you can keep seeking OOBE while realizing that you are on the path for all of these other experiences that are equally or more valuable.
