Ven. Bodhi translates dhamma as “phenomena”.
B.Sujato has “principles”:
They meditate observing an aspect of principles—keen, aware, and mindful, rid of desire and aversion for the world.
from standard sammā sati formula:
(derived from ven. thanissaro’s)
- dhammā-(a)nupassī
dhammesu dhammā-(a)nupassī viharatiMental-qualities-as mental-qualities he abides-in, ātāpī sampajāno satimā,(refrain:) ardent, aware, mindful, vineyya loke abhijjhā-domanassaṃ;Putting-away worldly greed-(and)-distress. evaṃ kho, bhikkhave, bhikkhu sato hoti.Thus indeed, monks, (a) monk {is} mindful ****.
Ven. thanissaro uses “mental qualities” for dhamma. I think Thanissaro and Bodhi’s translation has been unduly influenced by late Theravada. The more comprehensively I’ve scanned the EBT’s, the more I’m convinced the primary meaning of “dhamma anupassana”, is closer to B. Sujato’s “principles”, by which I assume he means Principles according the truth of reality discovered by the Buddha.
But I’d go even farther and say, “dhamma”, in the context of 4sp (satipatthana, i.e. right remembering/sati), is not just any principle, but specifically, the dhamma principles that directly lead to viraga, nirodha, patinissago, nirvana. What that exact dhamma is in any given moment, will vary according to the skill level and stage of the practitioner.
dhamma as “phenomena” is too general and misses the point.
sati means “remembering”, or recalling to mind frequently what one has memorized by heart. establishing the 4th of the 4 rememberings (dhamma anupassana), means that we are frequently to remember, to bear in mind in this very moment, the particular dhamma/teaching/principle that will right now be the most pertinent to leading to viraga and nirvana.
In the last 4 steps of 16 APS (anapanasati), are explicitly stated to correspond with 4sp’s dhamma-anupassana.
13. anicca
14. viraga
15. nirodha
16. patinissaga
And several passages in the EBT, we see those exact 4 words, in that exact sequence, as the final steps leading to the moment of realizing nirvana/arahantship. (SN 54.8, AN 7.61).
There are also some sutta passages where the Buddha defines “dhamma” as those teachings that lead to dispassion/viraga.
Conclusion: Even though “dhamma” has such broad meaning like the english word “thing”, I’m almost 100% convinced now that dhamma in dhamma-anupassana is not phenomena or mental qualities. dhamma contemplation in 4sp means employing a specific teaching that is most relevant and necessary in the moment to bring one to realization of nirvana.
I don’t know the most concise way to express that, but I think “principle” or “teaching” is still too general.
maybe “contemplation of dispassion-principles”.
