What is mysticism?
I have looked at the introduction to the thread and think that my own interest in mysticism is probably in the sense of category number 7, of hidden truths. One of the books which I am reading currently is 'Secret Teachers of my Western Tradition,' by Gary Lachman. In it, he does look at mystical ideas, such as those of Blake and Goethe. Lachman, who was also drummer in the pop band Blondie, is one of my favourite writers, and also wrote, 'Jung the Mystic', as well as others, including one on the ideas of Rudolf Steiner.
I spend a lot of time reading these books, but I do see it more as a process of gaining wisdom rather than declaring definitive truths. At times in my life I have almost felt 'beaten up' psychologically by people from religious or secular backgrounds who have tried to enforce their ideas. So, when I write on this site, I approach it with a view to meaningful exchange of ideas, but with a certain point of caution. I think that it is a problem if people claim to know more, or have the correct way of seeing than others.
However, that is not to say that there are not methods of analysis or certain knowledge which can be shared. However, I think that the quest which underlies the questions underlying the mystic quest goes beyond the actual ideas. Lachman says,
'Reading is simply more than simply looking at the pages and reflecting them. I have to make the mental effort of absorbing the words, connecting them, and assimilating them to my experience'.
I think that he is capturing the way in which ideas are not independent from our lives. They have to be absorbed subjectively, in order to become insights, rather than just remain as philosophical arguments. I am not saying that philosophical discussion is not an important aspect of this process, but it goes deeper and beyond the surface of the actual arguments, in the development of meaningful insight.
