“If the dhāraṇī mantra has been recited a total of 100,000 times, you will see buddhas, bodhisattvas, śrāvakas, and pratyekabuddhas in a dream, and see a dark substance vomited from your mouth. If you have committed serious offenses, you should recite it a total of 200,000 times. Then in a dream you too will see buddhas and bodhisattvas, and also see a dark substance vomited from your mouth. If you have committed any of the five cardinal sins, you may still not yet have this auspicious dream. Then you should then recite more, a total of 700,000 times to attain such a sign. In a dream you may even see a white substance vomited from your mouth, like rice paste, in the similar way. These are signs of purity and cleanliness indicating that the karma has been extinguished.
