The practice
The verse describes closing off the senses so that attention has nowhere outward to go, and a subtle energy then rising slowly up the centre of the body with a sensation the text compares to an ant walking on the skin, ending in great delight.
What it works on
This is a description of an experience rather than a set of steps, and the tradition treats spontaneous energy movement of this kind as something to be accompanied rather than pursued. Shoonyaka presents it for recognition, not as an exercise to attempt.
Notes
- If something like this arises during ordinary sitting, the traditional advice is simple: do not chase it and do not resist it. Keep the practice you were doing.
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.
