I had a thought...
If in the astral plane karma is a little bit more exaggerated, and some meditations require being unspoken, as in, to be heard from within at a certain chakra so it reverberates into the non-physical realms.... what if you did an Ohm or Mah mantra while in the astral plane? Would it manifest a lot more effectively that way? Logically it seems to make sense. I full intend on trying this out the next time I project, though I really don't know what the effects might be... Any thoughts? Anyone?
