While reading Sayalay Susila's "Unraveling the Mysteries of Mind and Body Through Abhidhamma" I noticed this sentence:
"New practitioners, when developing their concentration on the meditation object, owing to the weakness of mindfulness, sometimes let their minds fall into the bhavanga state."
I thought the ideal of samatha meditation was to reach the still points. Maybe I'm misunderstanding how optimal calm can happen while the mind is "processing" things outside of the bhavanga intervals. Thanks for any pointers.
