There are many arguments as to what is or what is not the Qabalah, and indeed the right ways of accessing it. However, one aspect of it - The Tree of Life - is so versatile it encompasses all things for all people, and therein lies its infinite value, for whether we are of a certain religious persuasion, an atheist, agnostic, materialist, philosopher, psychologist, scientist, or simply just a querent, it acknowledges such variety of opinion, yet opens doorways of new perception that help us to really know and understand where we come from, what we believe in, and above all the reasons why we do so.
The key phrase for the Qabalah is 'Know Thyself', which may seem a simple statement - and indeed it is - yet those who study it find themselves not only in a never ending field of self discovery, but also of the world and universe around them.
Whatever way we look at it, from the simplistic to the complex, in responds to the 'level' of our personal understanding, is open to challenge, and holds many answers that have hitherto defied explanation.By studying the Tree of Life, we get in touch with just one aspect of this remarkable subject, but perhaps this is the most important area, for it is directly associated with ourselves in the personal sense, as well as part of the human evolution.
The Qabalah, therefore, is arguably not a religion but more a philosophy and, although it does not purport to make life easier, it does help us ensure that we can make it much better. It's value is in the use of The Tree of Life as a psychological 'tool', and its study can be likened to taking a Degree in Life.
