Thank you. I will be careful in my astral work and i will read as many books as i can and ask for an advice some people. But i hope i will have no such problems because of my every day one hour or more of meditation, 30 minutes of surya namaskara, 1 hour and a half of pawanmuktasana, almost two hours of yoga nidra an so on. Even if i die i hope i will learn astral travel and other stuff in another life. I'm not afraid of death and i'm aware that i can die from two hours or tomorow; no one knows. But of course i am watchful on every step and try to take from day as much as i can. I have already orderd few books on astral travel and astral projection so that i will learn and of course i will get in touch with forum if i will need an advice .
