大乘起信論略述 2.181

2.181

[Treatise:] Therefore one should ... because wholesome roots increase. [Exposition:] This explains the method for remedying obstacles. "Therefore one should prostrate," etc., generally clarifies the expedients for removing obstacles. Just as a indebted person relying on a king cannot be touched by his creditors, so the practitioner prostrates to the Buddhas; being protected by the Buddhas, he can escape all obstacles. "Repentance," etc., clarifies the methods for separately removing the four obstacles: the obstacle of all bad karma is removed through repentance; the obstacle of slandering the true Dharma is removed and eliminated through entreaty; jealousy of others' superiority is remedied by sympathetic joy; clinging with delight to the three realms of existence is remedied by dedication of merit. "Constantly without cessation, one can avoid all obstacles," etc., concludes the preceding expedients that avert obstacles and give rise to the wholesome.
