Rather than practising astral projection at night, right before you go to sleep, start in the early morning hours when you're still feeling drowsy. Some say that it's easier to reach the necessary state of relaxation and heightened awareness around dawn. Yet it is possible to astral travel at any time so there are no hard and fast rules. It is a personal preference or simply astral traveling when we feel empowered to do it. Astral projection requires a state of deep relaxation, so it should be performed in a part of your home where you're completely comfortable. Lie on your bed or sofa and relax your mind and body.  It's easier to perform astral projection alone than it is with someone else in the room. If you usually sleep with a partner, choose a room other than the bedroom to practice astral projection. A good time to do it is when no one else is in and make sure no one is going to walk into the room when you're in astral flight. Draw the shades or curtains and rid the room of distracting noises. Any type of interruption could disrupt the state of relaxation you need to achieve. Position yourself on your back in your chosen room. Close your eyes and try to clear your mind of distracting thoughts. Concentrate on your body and how it feels. The goal is to achieve a state of complete mind and body relaxation.  Flex your muscles and then loosen them. Start with your toes and work your way up your body, gradually making your way to your head. Make sure every muscle is completely relaxed when you are through. Breathe deeply and exhale completely. Don't hold tension in your chest and shoulders, just relax. Focus your mind on your breathing. Don't get carried away with thoughts of outside worries, and don't get preoccupied yet with the idea of your soul projecting from your body. Just let yourself sink into relaxation. It can be helpful to use a quartz crystal to raise and speed up your vibrations as preparation. Gently hold the crystal on your third eye slightly above the centre of your eyebrows with closed eyes and breathing deeply. Feel the vibrations and your head clearing; you can envision golden, white, purple or any colour light if you like. During the meditation and astral travelling you can hold the crystal in your hand or place it on your chest or abdomen. The crystal will empower and protect you because of its high vibrations; negative energies have lower vibrations.

Summary:
Start in the morning. Create the right atmosphere. Lie down and relax.
