Q11: Venerable Sir, how does a yogi keep the balance between concentration and energy by noting “rising and falling?”

问11：尊者，禅修者如何通过观照“起、伏”保持定与精进的平衡？

Noting “rising and falling” demands neither too much concentration as it is not a monotonous kind of object, nor excessive enthusiasm as it’s only two types of object to note.Thus, the balance can be kept between concentration and energy.

观照“起、伏”既不需要过度的定力因为它不是单调类型的所缘，也不需要过度的热忱因为只有两种所缘需要观照，因此能够保持定和精进的平衡。
