on what the Buddha taught
Saṅkappa is often translated as thought.
We got thoughts all over the path... it seems so vague.
What we can read is that there are the three right ones (nekkhammasaṅkappo, abyāpādasaṅkappo, avihiṃsāsaṅkappo) and the three wrong ones (kāmasaṅkappo, byāpādasaṅkappo, vihiṃsāsaṅkappo). We can think about renunciation, good-will, harmlessness but when we are actually (trying to be) harmless now that is a bit different. To me, saṅkappa means attitude.
With right view, right attitude.
Saṅkappa attitude.
