注大乘入楞伽經 5.20

5.20

Because fools above discriminate false phenomena and generate the lineage of the śrāvaka vehicle, and yet within the śrāvaka Dharma there are distinctions among the four fruits, Mahāmati therefore brought up the distinctions among the four fruits to inquire. "Practice" refers to causal practice; the causal practice cultivated by a srotāpanna is aimed directly at advancing toward the fruit of an arhat. Since faculties are sharp or dull, there are distinctions.
