“Myō” means revival. For example, when a mother crane calls out to her dead child, “Shian,” the dead crane will come back to life. When a poisonous bird called chinchō enters the water, fish and clam will die from the bird’s poison, but the touch of a rhinoceros horn will bring them back to life. Similarly, when the Two Vehicles of śrāvaka and pratyekabuddha, (who were nearly dead because their seeds of Buddhahood were roasted in various sūtras,) icchantika, women and others who uphold the character “myō,” their dead seeds will be revived and they will all be resuscitated.
