84000 = 3

All 84,000 skillful means of the Buddha's teachings
are to lead you
to realise only the 3 Universal Characteristics.

1. Everything changes. (Anicca)
2. And because everything changes, there is no self. (Anatta)
3. And because we do not see the above, we suffer. (Dukkha)

The Dharma can be as "complicated" as all the 84000 teachings altogether,
and it can be as simple as 1,2,3. reply
