Or it may aid in processing traumas that were blockades to meditation, with a net result of it being easier to do meditation practice afterwards even without psychedelics. It's all speculation until further research is done into how all this works exactly, no?
But FWIW, this research seems to suggest one does not need to keep using psilocybin to have its long-lasting beneficial effects:
> Compared with placebo, psilocybin enhanced post-intervention mindfulness and produced larger positive changes in psychosocial functioning at a 4-month follow-up, which were corroborated by external ratings, and associated with magnitude of acute self-dissolution experience
