Physical, emotional and mental health are key in learning how to astral project as they provide a strong foundation for practicing all the techniques. Balance and moderation in every aspect of one's life never hurt anyone and can only make things easier. Developing clairvoyance and embarking on astral travel has more similarities than one might think, so the general advice applies to both. The practice of it begins with choosing a quiet and secluded spot where you can lie down comfortably and relax. Deep relaxation of every part of your body (and mind) is essential. The next step involved is reaching an almost hypnotic state by letting the body approach sleep without completely losing human consciousness. This fine balance between wakefulness and sleep is the trigger for all astral projection techniques. Oftentimes, as the astral body prepares to separate from the physical, vibrations are felt throughout. Just as the separation is about to occur, you need to firmly but gently use your mind to control and move your astral frame. Stand up, look around, walk across the room, then try to look back at your physical body. It should be lying where you left it, motionless as if asleep. Learning how to astral project will, of course, be a bit of a challenge at first, but be persistent. As you get better at it, try to leave the room (in your astral form), go to the next one, examine an object of your choice, remembering every detail. Once you're back in your physical frame and fully conscious, go and check whether your astral perception was correct. This way you will make sure that you are really having an OBE and not living a mere fantasy.
