Delusion

Well after about two weeks I managed to complete my reading of the Surangama Sutra; I found it very difficult going and quite difficult to comprehend, but I think the Sutra explains how our minds in a non-enlightened state lead us to be deluded about everything about and within us and the craving for these delusions and the "laws" of causality result in us being "caught in the trap of samsara".  This is a Mahayana Buddhist and probably a Pure Mind sutra, and so has much that goes way beyond my reasoning and deals with much that I'd call metaphysical (or maybe religious style doctrine) especially in the descriptions of the realms of hell, hungry ghosts etc. But do I think the effort in reading over 300 pages of quite dense and repetitive text was worth it...well I'm reserving my judgement on that one, especially as this was first sutra...I'm sure there will be many short summaries of the sutra available on the internet that are more easily digested and maybe I should have started there first.
