well what's safe? if your asking if you can die then No I don't believe you can die when you astral project. lot's of people do it every day even, you can do it when you sleep but don't know. If anyone has died from Astral projection we would not know as how could they tell us? I've never died. Astral projection is good for healing. No one can get into your body if that's a worry as we have our own sliver cord. The only danger would be if some killed you while you where gone but if that happened you'd just continue in the astral world. Why would you get killed thou as you'd be in a safe place, like home. I can't think of any other questions normally asked. Fear holds us back once we get rid of fear, we're good to go.
ok have you tried the rope technic? Lie down, where you won't be disturbed. Don't be afraid if you have fear, then don't even start. Till you get rid of your fear & relax then it won't work. Write spend a few moments in deep breathing & mediation. Not to long. When you ready begin, lie down, close you eyes, place your hands onto your knees. If you can reach, I put mine on my hips as I'm very short. imagine you a rope hanging down from the celing, see it clearly, imagine your arms, see them clearly, grab the rope & keep pulling it. You may get dizzy at 1st, don't worry, after sometime your eye lids may flicker or may not (we're all different) don't panic. You should get buzzing in your head, vibration under you, don't panic! Once you get to the point where your head in winning, pull up, your head should come out 1st, pull up climb the rope to the top of the ceiling. Your not out, see your out, how does it feel? Notice everything. I have another good technic. imagine your in a fair ground at night, go over to the roller coaster, get in a cart, ride the roller coaster, see every bit of the roller coaster, feel all the turns of the roller coast, your bed should feel like it's moving. Once your ready fling open the door of the cart & fling out. Your now free! When separation has accrued we need to learn to stretch out of our bodies. A lot of people either pull up or roll over till their astral body hits the floor. Remember banish your fear or you wont go any where as fear hold us back!
