i think that for someone who is dabbling on their own, learning from a group may be beneficial, then you can work out what suitd you best and decide to maintain it independently. a bit like a diet..works better if more of you are egging (yum) each other to stick with it.. i have used cds (...
agree with half time pies... find a local group. its soo much better learning via group meditation and then you can choose what suits you. mine is done via my local spiritual shop...wacky shop..most places run courses etc.. good luck
