5.35

[Treatise:] Or they manifest transcending grounds […] inconceivable.
[Commentary:] This is the virtue of extending or shortening [time] in accordance with faculties. Hearing that kalpas are long, minds would backslide; therefore, they manifest transcending the grounds, stating that there is swift attainment. "Or they say, 'I, in […]'": this clarifies the virtue of extension. Hearing that kalpas are few, they would not be diligent; therefore, they speak of a long duration to arouse their vigour. "Able to manifest such […]": this concludes the multitude of virtues. Their wondrous activities are inexhaustible, beyond the path of mind and speech, and all are for the sake of benefiting sentient beings.
