I've only gotten near the 1st Jhana so far, but I found "Focused and Fearless" by Shalia Catherine to be useful. It teaches all of the related concepts ( names and descriptions of various states of mind, etc ) without dumbing things done, yet is very clear. She offers loads of exercises, but the basic technique is to do anapanasati with the difference ( from insight practice ) of letting go of distractions as opposed to being aware of them and watching them pass.
In reading the scriptures, there are two kinds of mistakes:
One mistake is to cling to the literal text and miss the inner principles.
The second mistake is to recognize the principles but not apply them to your own mind, so that you waste time and just make them into causes of entanglement.
