SC is pretty awesome. A similar topic showed up on a pop up window, I clicked the link to a previous discussion thread, and it gave me the answer I was asking.
akusalamūlasuttaṃ n (AN 3.70)
“tīṇimāni, bhikkhave, akusalamūlāni. katamāni tīṇi? lobho akusalamūlaṃ, doso akusalamūlaṃ, moho akusalamūlaṃ.
Is rāga and lobha, can they be interchanged synonymously when we see the 3am (akusala mula) together?
edit, addition:
So to confirm, is 3am the official EBT designation? Is it known by other names? In the fire sermon, those 3 are the fire of rāga, fire of dosa, fire of moha.
I also just noticed, 3am (akusala mula), reminds me of 3a.m., which happens to be the time Ajahn Mun and Ajahn Chah say we should be awake and engaged in combat with the 3am.
