The yopgapaṭa (ayogapaṭṭa) occurs in two or three relief scened at Sāñchī Stūpa one.  The example included is in  the top panel of the south face of the north pillar of the west toraṇa. While it is impossible to identify the specific religious practice of the yogin in the relief, he could be a Jain as we know that the were active and producing their own are as early as the first century BCE (at Mathura) and possibly earlier, i.e. the Lohanipur torso from the mauryan period.

Dear List members,

Jaina monks, or their followers, are often depicted sitting with a strap going around their bodies and legs. (a few years ago I saw this contraption in a posh interior decorating shop in Leiden as an alternative chair!) Could anyone tell me if this strap, or sitting supported by this strap, had a (Sanskrit, MIA or NIA) name. By the way, it is not a particular Jaina practice. If I remember well, the strap can also be seen on, for instance, the Borobudur.
