Hmmm, I don't remember what I might have said, but I have the idea that it would be that the practices that we engage in to develop the ability to travel on purpose, will tend to support or stimulate whatever natural psychic abilities we might have.
I also think that a natural clairvoyant will prob. have very clear RV images, while a tactile person will tend to have OBEs to the RTZ with the sensations that go with this. But I may revise this, since I'm more of a tactile person and I have no more sensations in the RTZ, and lots of visions now, which is reversed from when I started learning to induce them. So there's an element of change apparently involved here.
IMO, the main reason that I give for being a 'natural projector' (since a very early age) is that I'm a light sleeper and wake up a lot during the night- always have, and I think this is why I remember most of my projections, and have since I was younger.
Not sure if this answered your question, though.
