Thank you for the recommendations
I was wondering what you meant by not taking everything 100% What if I interprate things incorrectly?
Like the last poster said, you have to gather information for yourself and figure things out based upon looking for good sources of information. What I mean by what I said was that most books on jhana offer certain perspectives on jhana and there are quite a few. For instance, you brought up the book by Ajahn Brahm 'Mindfuless, Bliss and Beyond'. Now I have great respect for Ajahn Brahm and I do agree with much of what he says, but when it comes to jhana we see things differently. Ajahn Brahm holds the Vissudhimagga (which you can consider a commentary and explanation of what the Buddha meant on different topics) to be authoritative. I, on the other hand, do not consider the Vissudhimagga to be to be right when it comes to the issue of jhana. It says quite a few things that seem to be quite off on what the Buddha said and did and the main problem is that it seems to make the first jhana more like the fourth or perhaps formless jhanas of the suttas.So, having read Ajahn Brahm's book I'd say it's not my first choice on jhana. Although it does have some good parts in it about why jhana is important. The trouble is that it's really only a small portion of the book. To be fair Shaila Catherine uses the Vissdudhimagga, but seems to rely more on the suttas and her idea of jhana seems closer IMO to the suttas than other books I've read. Ven. Gunaratana's book is good too. I've read it and it's a good intro, but I don't think it contains enough depth. If you can purchase both Shaila's book and Ven. Gunaratana's then I think you would be on good ground to understand what jhana is all about. If you have any more questions feel free to ask. I hope again this may be of some benefit to you.
