The practice
The verse describes standing over a deep well and looking without blinking into the hollow, so that the mind, given depth with no bottom to find, empties and dissolves.
What it works on
Depth does something width does not: it removes the reference plane. This is the vertical counterpart to the open-plain and open-sky practices, and traditionally one of the most abrupt in the text.
Notes
- Any deep space seen from safety serves the same purpose — a stairwell, a tall atrium, a valley seen from behind a barrier.
Practise gently
Shoonyaka offers educational and contemplative material, not medical, psychological or religious authority. Nothing here diagnoses or treats any condition. Stop any practice that leaves you dizzy, frightened or unwell, and treat a strong reaction as a reason to rest rather than to push on.
