The central principle of the Qabalah is respect for oneself and equal respect for others. This respect depends upon the acceptance of oneself and others for being as we are. We may intend change but we do not require it.
Deep relationships built on a ground of mutual respect are the basis of healing.
The key to understanding ourselves is through the nature of relationship. The tree of life, built as it is upon correspondence and relationship, provides the structure for this key. The work we then do with the Tree is equivalent to putting the key in the lock and turning it. The relationships between us and the world, in all their different facets, are what provide restriction and freedom, peace and war, all the different manifestations of harmony and discord we experience in our world. This is equally true intrapersonally and interpersonally.
