大乘起信論裂網疏 6.147

6.147

由有自心一體三寶，方有世間一切三寶。若謗此法，即是斷三寶種，罪報之大甚於五逆十惡也。

Because of the one-essence Three Jewels of one's own mind, all the Three Jewels of the world exist. If one slanders this Dharma, it is precisely severing the lineage of the Three Jewels; the gravity of the karmic retribution is greater than the five heinous deeds and the ten unwholesome actions.
