Checkered floor.
The human life is full of good and evil ... where we step and place ourselves can depend on the experiences we have. Sometimes these experiences are imposed on us.
Looking at that link :
This is explained in the first degree of Freemasonry. It is essentially a symbol of a dualism view , which is not that evident in Blue Lodge ( or 'preliminary' Masonry) , but appears more in 'advanced' Rites where kabbalistic and alchemical ideas on dualism are discussed and presented.
The lecture pertaining to the 15th Degree, Knight of the East and West, discusses the idea of duality or good and evil as a conflict. Pike writes “God is great, and good, and wise. Evil and pain and sorrow are temporary, and for wise and beneficent purposes…Ultimately, Good will prevail, and Evil be overthrown.”
Wilmshurst, “The Meaning of Masonry.' : “The dualism of these opposites governs us in everything, and experience of it is prescribed for us until such time as, having learned and outgrown its lesson, we are ready for advancement to a condition where we outgrow the sense of this chequer-work existence and those opposites cease to be perceived as opposites, but are realized as a unity or synthesis.”
Also the floor is on what we stand, our base , one of the most insidious thing about this crime (sexual assault) is that it can 'knock ones legs out from under them' ... make it difficult to regain balance, effect the psyche deeply and make it hard to make a recovery or a transition to where " we are ready for advancement to a condition where we outgrow the sense of this chequer-work existence".
Its all very well to wax philosophical about such things and transcend duality ... but this type of setback might not be able to be dealt with ... especially by advice from people that have not experienced it ... the sexually abused need a lot of empathy from us and professional help and counselling for them . You cant 'force' someone into a 'higher' lodge or higher level of acceptance of crimes committed against them ... I would not be offering any Masonic or Tarot reader 'platitudes' to them.
