Working with sloth-and-torpor (thina-middha)

Dullness and sleepiness in meditation require energising antidotes, not more settling.

Why it works

Sloth-and-torpor is an under-arousal state — the meditator has insufficient cortical activation to sustain attention. Gentle settling and breath focus deepen the under-arousal; the correct antidotes are those that introduce mild activation without agitation: opening the eyes, standing, walking, vigorous attention to breath, or introducing a bright visualisation object.

How to do it

1. When dullness arrives, open the eyes slightly and look downward at a 45-degree angle.
2. Straighten the posture — slumping deepens torpor.
3. Switch from breath focus to a more active object: the sensations in the soles of the feet, or walking meditation.
4. If very drowsy, stand and do several minutes of walking meditation before returning to the cushion.

Evidence

Postural upright position increases cortical arousal; walking increases alertness relative to sitting — consistent with the energising antidotes prescribed for torpor. (mechanistic)

Peper & Lin study posture and depression, not meditation torpor specifically; the alertness mechanism is shared.

Common mistake

Trying to push through torpor with more concentration effort, which is like trying to see better in a dark room by squinting harder.
