Best mantra to induce OBE whilst relaxing and visualizing?

[SkepticBoy]

Is there a best mantra to use whilst one is lying there waiting for an OBE and relaxing? does anyone have one in mind they always use? some recommendations pls.

I'd help but all I do is my breathing exercise and slowly lower myself deeper. From my experience on meditation though I would say any simple thought you can hold your mind on is good. Even something as simple as a single syllable.
