Which are the best books and/or articles for practicing the jhanas?
I have this book by Ajahn Brahm (Mindfulness, Bliss and Beyond) which has probably the best description and methods of the topic of Jhana but even better meditation techniques to achieve Jhana. Link below. Hope this helps.
I found the following to be very useful:
Shaila Catherine writes with a precision and clarity that is missing from most texts on the subject. Great meditation manual as well as guide to the Jhanas. Shaila and Ayya Khema mentioned below seem to write from deep personal experience and this is backed up by their personal histories of practice.
Ayya Khema combines clear and concise instructions that are, for the most part, are a commentary on sections of the Potthapada Sutta that expound on the Jhanas.
I would recommend the book "Practicing The Jhanas" by Tina Rasmussen and Stephen Snyder.
They were both students of Pa Auk Sayadaw and undertook a Samatha Meditation Course under his guidance. Here they achieved the 4 material jhanas and the 4 immaterial jhanas.
The book is streamlined and direct. Not much beating around the bush. They often refer to their own practice and how they trained under Pa Auk Sayadaw. This functions well.
They give lots of useful information and guidance regarding the practice of the Jhanas. I have taken a screenshot of the table of contents so you can see what the book contains.
