To anyone who's read anything about magic and modern hermetics will have come across the Lesser Banishing Ritual of the Pentagram. Its a ritual that is advised for people across whatever magical path to work with for a variety of reasons; visualising, daily ritual, purification, intoning, directing the will, routine, the subtle changes which occur due to time, place, mindset. Its powerful and it works.
A lot of books note the ritual and leave the rest to the practitioner to work out, that through working the ritual you personally unearth meaning, connection and (perhaps) learn more about yourself and your own psyche and discipline through the process.
And yet, some of us need a bit of a head-start to make those connections, to realise there is more there than meets the eye.
Its short but sweet, full of detail and possibilities that even the seasoned practitioner may need to be reminded or or see things in a new light.
I highly recommend this, and its great to read on Kindle too. I would love the author to write more about such subjects :D
