四、用心主境治病者，有師言：「心是一期果報之主，譬如王有所至處，群賊迸散。心王亦爾，隨有病生之處，住心其中，經久不散，病即除滅。」又師云：「用心住憂陀那。此云丹田，去臍下二寸半，多治眾患。」又師云：「安心足下，多有所治。」其要眾多，今不具說。

Fourth, curing illness through directing the mind to master an object: one master said, 'The mind is the master of a single span of karmic retribution. Just as wherever a king arrives, bands of thieves scatter and flee, the king of the mind is also like this: wherever an illness arises, if one rests the mind there without scattering for a long time, the illness is eliminated.' Another master said, 'Direct the mind to abide in the udāna—translated here as the cinnabar field (dantian), two and a half inches below the navel—and it mostly cures various afflictions.' Another master said, 'Settling the mind beneath the feet cures many ailments.' Such essentials are manifold and will not be fully explained now.
