Vajradhara, I find it interesting that you describe Right Hand Path as the negative one, and Left Hand Path as the positive one.
In Western occultism it usually reversed. For instance, if you look up Left Hand Path on the internet you will find lots of Satanism resources. There are many (including me) who feel the whole Left/Right Negative/Positive Evil/Good way of looking at things is a false dichotomy, but it is there especially in monotheist-dominant texts and systems.
There are also some who try and avoid the evil/good dichotomy while retaining the left/right labels by describing left as being independent and right as being based on strict following of rules.
Greetings Bgruagach.
While i am not Vajradhara, nor do I play the part on stage, screen or message boards, I shall hazard a reply to your queries.
Right hand and left hand orientations to certain aspects of life are not uncommon.
A strong right-hand is considered as a person who is dependable in almost all situations, especially those involving hazard or immanent threat to one's life, way of life, ideals, etc. This dependability is so much so that they may forfeit their own life in the process, should it be necessary. One may also note that in affairs defensive and military, a strong right-hand is the party of favor. Could this be, quite simply, that right-handedness is norm?
On the other hand, the left, we find referenced in the Tao Te Ching that this is the honored place of the advisor against conflict<1> or war and for change, especially of a peaceful and beneficent nature.
Yet the "Western" occult view may also be seen as merely an extension of that
portion of human nature to view, at first, that which is different, i.e. "not one of us," as a potential danger. Thus a left-handed person, being different from the norm of right-handedness, may be viewed as a potential enemy. It should not be all that surprising that for many cultures that the word(s) for "stranger' and "enemy" are similar particularly at the tribal level.
The delicate act of the decision maker is to prevent the hawk from eating the dove, its true nature, and the doves from eating the eggs of the hawk. For each of these councilors have their place, voice and function. One might say that they, like Good and Evil <2>, are inter-dependent and co-arising.
