I’m not arguing there is. I think if your main practice is filled with passion and is decidedly interpersonal, this will lead to you have different experiences and expertise, states of mind, than someone who has a detached, not interpersonal, emotionally calm practice. In a sense like any two people learning two quite different skills will, when they perform their art or job, will perform differently. Perhaps some understandings will be the same, perhaps not. But it seems likely to me that if one set of practices is intentionally engaging the amygdala as central to the practice and the other is detaching from it, what one experiences down the line, and what one is like down the line will have significant differences.
And then, also, different understandings of the role of emotions and what one is striving for.
This also fits my experience of the people who have been practicing these traditions for a long time. They have rather different presences, especially if we include pagan/indigenous/shamanistic practitioners creating a third distinct mode, different ways of relating (as tendencies in the groups) and different insights.
It’s not a coincidence that Buddhism tends to no self in ways that other practices do not. That some traditions have a no self rebirth and others a full on reincarnation. Or that the Christians have no reincarnation and a heavy moral focus. Or that the submissive self effacing practices (which include a kind of fatalism) in Islam leads to the way Muslims live and behave and relate to death.
Different practices, different parts of the brain, different foci.
I feel like it’s a cliche that they all lead to the same place, same beliefs.
