密呪圓因往生集 1.39

1.39

若此心呪誦十萬遍，即見一切如來；誦二十萬遍，得見一切佛土；若誦三十萬遍，得成一切曼荼羅，一切真言法悉得成就；乃至若誦一百萬遍，得一切如來灌頂佛地，與一切如來同會。若造五逆罪、誹謗聖人、誹謗正法，應入阿鼻地獄者，誦呪一千遍，所作罪業悉皆消滅，得不退位，悟宿命智得六根清淨，兼獲世間種種事業隨意成就。

If one recites this heart mantra one hundred thousand times, one will immediately see all Tathāgatas; reciting it two hundred thousand times, one will behold all Buddha lands; if one recites it three hundred thousand times, one will accomplish all maṇḍalas and all mantra rituals will be fully realized; and reciting it up to one million times, one will attain the Buddha-ground of abhiṣeka from all Tathāgatas and assemble together with all Tathāgatas. If one who has committed the five heinous crimes, slandered the noble ones, or slandered the True Dharma, who is destined to enter the Avīci Hell, recites this mantra one thousand times, all the sinful karma committed will be completely eradicated, they will attain the stage of non-retrogression, realize knowledge of past lives, attain the purity of the six faculties, and additionally achieve worldly undertakings of all kinds according to their wishes.
