Happy to see Buddhaghosa on HN!

On a semi related tangent, I recently listened to the audio book of Ajahn Brahm's Mindfulness, Bliss and Beyond. It was pleasantly surprising to hear nimitta spoken about so frequently outside of the Visuddhimagga!

Ingesting Buddhist commentaries and practice manuals to provide advice and help with meditation is one of the few LLM applications that excite me. I was impressed when I received LLM instructions on how an upāsaka can achieve upacāra-samādhi !
