Now the question is, why are our olfactory systems so blindsided by this bottomless olfactory landscape? I feel like half of what I said he was already discussed here before but it's what's on my mind and maybe someone has another thought or two to add...
Phenomena like this I personally think can be very interesting to contemplate through the lens of evolutionarily psychology.
If you see a physical feature shared by a variety of organisms that seem to be deeply involved in their daily operations, you assume that that structure (say, a nose) represents the outcome some type of specific adaptation to the needs of survival.
Common / frequent psychological phenomena and "mental formations" can often be insightfully analyzed from the same perspective. Let's say that there is some universality to the potential for humans to become entranced by the fragrance of agarwood. What ancestral survival instinct or mechanism is this tapping into? Is it releasing oxytocin, because of the warm animal like fragrances and it resembles snuggling up to a loved one or beloved pet? Does it create a sensation of bonding like smelling the familiar smells of one's partner when in an embrace?
Or maybe it's just tapping into whatever drives us to crave fragrant foods, ripe cheeses.
it could also be tapping into an instinct to create/inhabit clean healthy environments - the smell of wood, smoke, baked goods, humans, flowers, resins, clean earth, terra cotta, petrichor, bodies of water, healthy livestock. all seem like facets of oud
The experience is so profound that I can't dismiss it as trivial
