पुटाकारौ करौ कृत्वा तर्जन्यावङ्कुशाकृती / परिवर्तक्रमेणैव मध्यमे तदधोगते
puṭākārau karau kṛtvā tarjanyāvaṅkuśākṛtī / parivartakrameṇaiva madhyame tadadhogate
Make both hands into the puṭa (cupped) form, with both index fingers shaped like an aṅkuśa; then, by the very sequence of turning, let the middle finger come to rest beneath it.
