You might check out Mahasi's Forty, which mentions the objects for contemplation, including an anapanasati, though a commentary influenced take:Insight meditation is incessant work -- meditate whenever you see, hear, smell, taste, touch or think, without missing anything. But to beginners, to note everything is quite impossible. Begin with several. It is easy to observe the moving form in the rising and falling of the abdomen. We have already spoken about it. Note without a let-up “rising, falling, rising, falling.” As your mindfulness and concentration grow stronger, add the sitting and the touching and note, “rising, falling, sitting, touching.” As you note on, ideas may come up. Note them, too: “thinking, planning, knowing.” They are hindrances. Unless you are rid of them, you have not got purity of mind and will not have a clear understanding of mind-matter phenomena. So, don’t let them in. Note them and get rid of them.
