The knowledge contained in `Angels' enables seekers to make real spiritual progress. It sheds a new light on the cabbalists' Tree of Life, describing its ten regions with the colours and divine qualities they represent and the virtues and forces they help us to develop within ourselves. Each region is associated with one of the ten names of God, corresponding to a divine attribute and inhabited by an order of luminous spirits under the leadership of an archangel.
`Meditate faithfully on the Tree of Life and your thoughts will no longer stray haphazardly. By referring frequently to the Sephirotic Tree you will be lighting your inner lamps, and those lamps will not only illuminate you, they will purify and strengthen you; they will also make you more beautiful and alive.
