Guptasana

Gupta means hidden, and the Gheranda Samhita describes the pose plainly: place the feet between the knees and thighs and sit concealed. The classical commentaries read the hiding symbolically — the limbs are drawn in and covered as the attention is drawn in and covered from the senses. Among the meditation seats of the tradition, Guptasana is the most withdrawn: nothing of the legs shows, nothing reaches outward. It is taught as a seat for pratyahara, the withdrawal of the senses that precedes concentration, and for the quiet internal practices of the kriya path.

1. Sit and bend one knee, drawing the foot in so the heel rests near the groin with the sole turned up.
2. Bend the second knee and tuck that foot beneath the opposite thigh, so both feet are folded out of sight under the legs.
3. Adjust until the sit bones ground evenly; use a cushion if the lower back rounds.
4. Place the hands in the lap or on the knees, close the eyes, and let the breath settle.
5. Begin with a few minutes and extend gradually as the hips adapt.

There is no direct research on Guptasana itself, but its mechanics are those of a deep cross-legged seat with the feet tucked under the thighs — substantial flexion of knees and hips with a compressed base. Ergonomically it suits practitioners with open hips and healthy knees, and like other stable seats it minimises the muscular corrections that disturb stillness. The tucked feet also keep the lower legs warm and the circulation contained, which practitioners in cold practice halls have long valued.
