practition — mysticism would be overlapping in areas of abilties such as levitation, Occultism would placate to secret societal order information such as the notorious skull and bones society for instance, or druidry (dark druidery could be a poster for hidden information but not* limited to practices such as divination either), Occultism is a often seen as a umbrella term to encompass these facets, in Esotericism you could apply the frameworks of the masons, or orthodox christian or buddhist monk monasteries as exhibit of this. I forgot a practice occult reference once the wrong music played i’ll comment with the answer if posi. update* belief in sirens would fall under Esotericism as well i think as an oddly specific example
