Do you find Sati, Sampajanna and Atappa in first Jhana?
Please refer to the following passage for description of above terms.
Thanissaro explains further:
As you do this, you develop three qualities of mind. One is mindfulness (sati). The term mindfulness means being able to remember, to keep something in mind. In the case of establishing the body as a frame of reference, it means being able to remember where you’re supposed to be — with the body — and you don’t let yourself forget. The second quality, alertness (sampajañña), means being aware of what is actually going on in the present. Are you with the body? Are you with the breath? Is the breath comfortable? Simply notice what’s actually happening in the present moment. We tend to confuse mindfulness with alertness, but actually they are two separate things: mindfulness means being able to remember where you want to keep your awareness; alertness means being aware of what’s actually happening. The third quality, ardency (atappa), means two things. One, if you realize that the mind has wandered off, you bring it right back. Immediately. You don’t let it wander around, sniffing the flowers. Two, when the mind is with its proper frame of reference, ardency means trying to be as sensitive as possible to what’s going on — not just drifting in the present moment, but really trying to penetrate more and more into the subtle details of what’s actually happening with the breath or the mind.
