First, hello all, and best wishes.
Second, Mystery says this in his 'Handbook of the Venusian arts':

"The martial arts and the venusian arts possess many parallels.

• Both are disciplines in dynamic social interaction, and each is for many, a way of life.

• Both rank proficiency; colored belts for martial artists and colored charms hung on black cords for venusian artists.

• Each also embodies a comprehensive mental element which is expressed through physicality."

Are these charms actually used? Are they used widely or only by followers of Mysetery? What do they look like? What colors are they?

Thanks
