I've posted some links on Twitter recently, to kabbalah.info, and wanted to delve into my perspective a bit here. I've read a little on the subject, and while I don't consider myself a kabbalist, I have been told by those who do (consider themselves) that my ideas are quite similar to theirs. I also draw from Christain mystics, Sufis, Zen, Tibetan Buddhism, Jesuits, Hindus, Athiests and more - so it would never be accurate to ascribe my understanding of the world and approach to life to any particular religion or philosphy.
I believe we are each created toward a specific purpose, designed for a specific role in the story of the Universe. That story is larger than any of us, yet each of us is essential to it.
We play that role, wittingly or not, according to our natures, our true or essential Will. We can better understand our Will, and better fulfill our role simply by following the internal compass of joy. What it is that makes us joyful, that satisfies us on a deep level, that makes us feel right and at peace and happy - that is our Will, or at least a part of it.
I find this sense of joyful purpose giving massage, especially when I am relieving pain. I find it in my writing, when an idea comes and I dive into it and let it flow through me, transmuting it to words in my own voice. The sensation is similar to lucid dreaming, taking control of an unconscious process and turning it in another direction.
I also find it at moments in other activities: noticing a beautiful contrast of a rusted yellow warehouse against a blue sky, watching my dog play, catching a glance between two people in love. The part of my purpose found in these moments is learning to appreciate the world.
We can also seek to understand how or own role fits with the larger dream of the Universe. This begins with the recognition of two things: 1) Each and every person has a role to play, and in this, we are all equal 2) the Universe is in constant communication with us, but we can only narrowly perceive the messages it conveys.
In addition to our bliss as a guide, everything around us is imbued with meaning - the arrangement of letters and numbers, the pattern in the branches of a tree, the "chance" crossing of our path with another person. Through introspection, study, openness and perception we can catch glimpses of this meaning, and as we do so, while continuing to follow our Will using our sense of joy as a guide, then we can progress spiritually.
A sense of the connection we have to the larger story is essential for the human race to survive. We can see from the echoes and repercussions occurring through the economies of the world right now. Our personal integrity is important, but it is also important to do our best to strengthen others - because if they fall, we will stumble. it is important, too, to remember that we cannot carry them, or try to direct them on the road to our own goals - because each person and each nation must discover their own Will, and learn to embody it. (I'm an advocate of micro-loans rather than charity or larger government loans.)
The most powerful thing we can do is to set an example by living our Will, and sharing our joy. In so doing, we inevitably inspire others to do the same.
