Astral Projection from "Advanced Magick for Beginners" by Alan Chapman

1. Lie down and relax.

2. Become aware of your imaginary body. Although
you are essentially imagining the body,
there should be an element of allowing the
sensations of the astral body to arise of their
own accord.

3. Now move around in your imagined form, see
with your imaginary eyes, hear with your imaginary
ears, etc. For some, astral travel comes
easy, but for a lot of people it can be quite difficult.
If at this point you are struggling to
'leave' the physical body and sense with your
imaginary senses, there is only one possible
course of action—practice! Some find it useful
to move a physical limb, remember what the
physical sensation felt like, and then use that
memory as a basis for moving the corresponding
astral limb, as an exercise in slowly building
up the astral form. However I very much
believe in simply repeating the above exercise
—usually, the 'knack' is suddenly gained and
the problems vanish, much like with lucid
dreaming. Keep in mind that you are trying to
access something that is already there, which
you already experience every night.

4. Explore! However, be cautious—not all astral
beings are who they say they are, and not all
beings mean well. Again, it is prudent to have
mastered a good banishing ritual. If you wish
to gain a greater understanding of a certain
idea, travel to its astral abode. For instance, if
you wish to explore Malkuth on the Tree of
Life, you can create a door with the necessary
attributes (such as the appropriate colour,
symbol, and material peculiar to Malkuth) to
take you there.

5. Be sure to return the astral body to the physical
body at the end of the practice
