"Any bodhisattvas whose thoughts are at present concentrated and directed toward the buddhas of the ten quarters, will, if they possess mental concentration, achieve all the exalted practices of a bodhisattva. What is mental concentration? Through compliance with the conditions for reflection on the Buddha, having one’s thoughts directed toward the Buddha; having thoughts that are not disturbed, thereby obtaining wisdom; not giving up energy; joining together with good friends in the practice of emptiness; eliminating sleepiness; not congregating; avoiding bad friends; drawing close to good friends; having energy that is not disorderly; in eating, knowing when one has had enough; not craving robes; not begrudging one’s own life; being solitary and avoiding one’s relatives; keeping away from one’s home village; practicing equanimity, mastering the attitudes of compassion and rejoicing, and the practice of circumspection."
