Here I announce a breakthrough in the neuroscience of the highly refined meditative states known as jhānas, revealing biological mechanisms of deep states of absorption that are profound, restorative, and deeply beneficial for the mind.
The jhanas are deep states of meditative absorption wherein the mind becomes deeply immersed in a meditation object and other aspects of awareness recede. These states are thought to: (1) deeply stabilize the mind; (2) serve as both a launchpad, and an inner laboratory, for investigating deep experiential aspects of the mind and perceptual reality; (3) help uproot unwholesome mental habits; and (4) offer rare glimpses into the genuine possibility a stable and reliable form of happiness. In this way, the jhānas are thought to prepare the mind for the meditative endpoint known as Nibbāna, or full Enlightenment.
Now, for the first time ever in the history of science, we have used cutting-edge brain imaging (7T fMRI) in a group of advanced meditators to measure the neural correlates of jhana-type advanced concentration absorption meditation (ACAM-J), including mapping the eight ACAM-J states evolving from joyful, energized focus to profound formlessness, where sensory content and self-referential thought fade entirely to reveal expansive, boundless awareness, and ultimately nothingness.
Here's what we found:
– Brain regions associated with self-monitoring and internal chatter (e.g., prefrontal cortex) quieted down, while areas involved world sensing and bodily awareness (including visual and midline regions) became more active.
– The brain’s usual hierarchy, from sensory-specific to high-level integrative areas, became more compressed, suggesting more unified, integrated brain function.
– Patterns of brain activity (eigenmodes) showed a U-shaped shift: early absorption states compressed cortical dynamics, while later states re-expanded, refined, and organized them.
– Changes in brain activity tracked closely with reported experience including equanimity, stable attention, clear awareness, and reduced suffering-related processes.
– The brain can volitionally enter coherent and stable states of deep awareness that are at the opposite pole from psychological distress.
Beyond potentially supporting mental health and wellbeing, these findings challenge mainstream models of consciousness with evidence that consciousness can persist in ways current models have yet to explain. Instead, the neuroscience of this ancient meditation opens an important new scientific window into the human brain’s inherent capacity to radically transform itself.

@algekalipso Exactly. Adyashanti’s story is a great example. Despite being an enlightened master, he was in severe pain for 20 years, developed PTSD and had to retire from teaching. He’s now on SSRI’s to manage the anxiety.
@ArashMadani I mean Hoffman will give you 3-4 outs but you need other guys to come out of the bullpen and pitch well. But yes Little is a liability. Don’t give him the ball. Period.
