Reply #28: yes...as upside down pentagram is banishing/negative...

and right side up is postitive/involking.
Same with windershins (left) or turning right..one is involking/drawing down/in (gathering) and the other is banishing/sending away/out. (dissapating)
Same with the Y but inside a circle it is much better as the circle holds the energy in..
The original Y in a circle was called the "Witches seal" or the "Crow's foot" and was the symbol of the Healer and of the One... but the Y had to have the straight line through the middle to be correct..so there is a three pronged end (for the three aspects/sacred trinity (yup thats where that came from but was for the three aspects of the Goddess (maiden-moon, mother, crone) as well as of the God (son/sun-father-wiseman).
The "Y" finger symbol used by the hippies is a Native American hand sign for peace.
This same energy movement is found in the western practice of hanging a horseshoe with the point up for luck...or down and the luck energy runs out.
If anyone wants to see for themselves the movement of energy on the mendella that you posted here...may I suggest they enlarge it...focus on it on their computer screens for a while by looking only at the center.
Then turn off the image and close the eyes while looking towards the middle of the forhead and they should be able to see the patterns of energy moving (they may already be seeing it by focusing on the center without turning the picture off and closing the eyes but it will help if they do this) :)
