No. The energy work is helpful but not essential. As long as you know how to do basic body awareness actions you will be able to use any OBE exit method better, which will improve your chances of getting out of body.

Remember, everyone projects out of body every time they sleep. The trick is to be able to remember OBE. Because, without the memory, if never happened, even if it did. To this end, a large part of my training and advice promotes the development of OBE memory recall. There are numerous steps involved to achieve this, including dream recall practice, and planning on a short 10 second OBE. This maximizes your chances of recalling an OBE. Subsequent OBEs can be progressively longer. See my book Astral Dynamics for more on this.
