俱舍論疏 28.15

28.15

論「又由此故至心於一境轉」，第三難也。如心所中定通其散位，散位非定，由修習故三摩地成名心一境。何不即以此修習力令心一境轉？

The Śāstra states: "Moreover, due to this... the mind proceeds upon a single object." This is the third objection. Just as meditative absorption among mental factors is present in distracted states, yet distracted states are not meditative absorption, and by force of practice samādhi is accomplished and called one-pointedness of mind—why not simply use this power of practice to cause the mind to proceed upon a single object?
