Hi,
I'm afraid, but I think, the only "method" to cope with learning material is to deal with it quite a lot. I thought for a long time, too, that there must be a method to "soak" all the wisdom in any written material w/out any effort, but unfortunately I'm no Superman. You must go through your material at least one time, better two or more. For this reason, the PR whole mind system is quite right, because there you go through the material many times w/out even recognising it. But your unconscious does! So the more often you go through your texts, the better your understanding will get. But there is a price to pay! With PR you can hold this price down, so you have more time for different interests!
