That is not quite correct. I just revised it as follows:
3. Tihetuka means kusala kamma done with alobha, adosa, amoha.
– Dvihetuka means kusala kamma done with alobha/amoha or adosa/amoha.
– Here, amoha means one would have wisdom at least at the minimum level, i.e., one would be aware of the laws of kamma.
– Ahetuka means kusala kamma done with alobha/adosa, but without comprehending the laws of kamma (i.e., one’s actions would have consequences in the future.)
