Furthermore, the Bodhisattva-bhadraśīla-sūtra says: If a bodhisattva does not read and recite the Tathāgata's correct scriptures, but reads and recites worldly treatises, literary verses, and commentaries, they commit an offense. They do not commit an offense if it is for the sake of debate to refute wrong views, or if two parts are Buddhist scriptures and one part non-Buddhist books. Why? To know that external treatises are deceptive phenomena while the Buddha's Dharma is true; to know worldly affairs; and to avoid being held in contempt by worldly people. Proven by this passage, if a student of the Buddha's Dharma completely neglects the internal to pursue the external, they commit an offense. Even if one understands principle and practice, one may only practice it temporarily; in order to subdue non-Buddhists, one must still feel revulsion and detachment from it, and advance in cultivating internal matters, ensuring they increase and excel. If one is partial and addicted to them, one destroys the true Dharma. Thus the Bodhisattvabhūmi says: If a bodhisattva abandons what the Buddha has spoken without studying it, and conversely practices non-Buddhist wrong treatises and worldly scriptures, this is called an offense, an offense of numerous faults, an offense arising from defilement. If a person of superior intelligence can quickly receive and study them and attain immovable wisdom, and each day always spends two parts receiving and studying the Buddha's Dharma and one part external treatises, this is called not committing an offense. If toward worldly treatises and non-Buddhist wrong teachings one cherishes affection, does not abandon them, and does not think of discarding them, this is called an offense, an offense of numerous faults, an offense arising from defilement.
