Hello Im new to the group and been tryin to study the Bardon books Guide to Hermetics and was wondering if any one could tell me, how long should you work on an exercise befor you move on to the next? Ive read it through and through but I cant figure it out I know it says that you shold master them befor you move on to the next but Ive done some of them in the past like the though focusing he describes and can do that fairly well, and all but have been wonderign about the general oponion on that, is it ok to start from another area of the book that you know you can do like the focusing then work from there? any information would be good thanks Brian
