I think I need to practice some energy work, so I will be able to control my body in RTZ zone, it's really hard to steer. ( I know from past experience in that zone ). I want to one day be able to project to people so strongly that they see my ghost in their living room. (People who know me and are familiar with this kind of stuff and who won't freak out.) It's a good skill, b/c even If I don't get anything productive done, at least I have a stronger will and good concentration and focus, which can rub over into other aspects of my life.
Ding! The more energy you are able to gather the longer you will stay out. I also have been trying to densify (add more mass) to my energy body when I astral project, so that people in the 3rd density level (our dimension) can see me.
