37.128

右手拓地（湯洛反此字更有異音今不取經意以右手掌按地是結印誦真言也）。

右手拓地 (pronounced with the fanqie 湯 + 洛 [tuò]. This character has other pronunciations, but they are not adopted here. The sense of the scripture is pressing the ground with the palm of the right hand, which means binding the mudrā and reciting the mantra).
