1.89

次用難堪忍，密印及真言，
而用結周界，威猛無能覩。
先以三補吒，風輪在於掌，
二空及地輪，內屈猶如鉤。
火輪合為峯，開散其水輪，
旋轉指十方，是名結大界。

Next, use the secret mudrā and mantra / Of Durddharṣa / To bind the perimeter, / Fierce and majestic, impossible to look upon. / First make the sampuṭa / With the wind-wheels inside the palms; / The two space-[wheels] and the earth-wheels / Are bent inward like hooks. / The fire-wheels unite into a peak, / Open and spread the water-wheels, / And rotate them pointing to the ten directions: / This is called binding the great boundary.
