4.310

經　「是故當知，持此陀羅尼者具大福德，已於過去無量佛所植諸善本，今得受持，於戒清淨不毀不缺，無有障礙，決定能入甚深法門。」

Sūtra: "Therefore, you should know that one who upholds this dhāraṇī possesses great merit and virtue, having already planted roots of good in the presence of immeasurable Buddhas in the past; now that they are able to receive and uphold it, their observance of the precepts is pure, unbreached, and without deficiency, devoid of any obstacles, and they will decisively be able to enter the profoundly deep Dharma-gate."
