4.88

三、呪術治病者，萬法悉有對治，以相厭禳，善知其法術，用之無不即愈。呪法出諸修多羅及禪經中，術法諸師祕之，多不妄傳。

Third, curing illness through incantations: all myriad dharmas have their counteractions to ward off and suppress [afflictions]; if one skillfully knows their methods and arts, there is none that is not immediately cured upon using them. Methods of incantation appear in various sūtras and dhyāna scriptures; the techniques are kept secret by the masters and are mostly not transmitted indiscriminately.
