I just had one small comment on the issue of the breaking of the vessels (שבירת הכלים) today.
Even though the Ari usually does not give exact reason for this, there are a few places that he does say openly the reason[s]. One thing he always mentions is the fact that the light was only the name 52.(יוד הה וו הה) He says if it had been 52 with 45 (יוד הא ואו הא) or just 45 alone there would have been no breaking. Also he says the "breaking" happened in the circles also of the name 52. [עיגולים דב''ן] I.e. it is not just that the breaking happening in the world of "dots" [נקודים]. Even when the dots expanded and became ten circles of 52 with inner and outer light, the breaking still happened.
I mention this here because I think that metaphysics should be returned to philosophy and as far as metaphysics goes I think the Arizal [Isaac Luria] does a good job
Hegel actually discusses the above aspects of the Ari. He was quite aware of Adam Kadmon where this breaking happened-- i.e. above emanation [אצילות] and in front.--if you go by the simple explanation/peshat in the Ari. You could also interpret the Ari like the Reshash-- but that is extremely complicated and for some reason when the Reshah רשש''ש (Shalom Sharabi from Yemen and later in Jerusalem) came to Yaakov Abuchatzaira in a dream asking him why he did not learn his book the Nahar Shalom, Rav Yaakov said he had a different path. (And his path can be seen openly in all his books--it is the simplest possible way to understand the Ari.)
