俱舍論疏 10.124

10.124

論「第三靜慮至何故不攝」，問。第三定樂唯依意故應名為近，在意分別應名為行，何故不名意近行也？

[On the Śāstra's statement:] '[Why is the pleasure of] the third dhyāna [up to] not included?', this asks: Since the pleasure of the third dhyāna relies solely on the mind, it should be called 'proximate'; and being a conceptual differentiation in the mind, it should be called 'investigation'; why is it not called a mental investigation?
