Tenggerese dukun has distinctive function and role than dukun from other community outside Tenggerese, such as Javanese, Madurese and Osing. Outside Tengger, dukun is person considered of having supernatural power to heal patients or to make people sick. Dukun that can heal sick people is called as dhukun cilik. While dukun Tengger is a chosen one as custom leader and as religion leader. Dukun Tengger has authority and duties to lead meditation, religious ceremony, custom ritual, and as an ulema or priest. In Tenggerese community, Tenggerese dukun is called as dhukun gedhe. In executing his call, dukun is assisted by legen, dhandhan and tiyang sepuh.

Until today, though they convert Hindu Dharma, Tenggerese dukun still maintains tradition in worshipping god that resides in Mt Bromo, a sacred ceremony handed down by their ancestors. For western experts, this tradition is called as animism, tradition to worship invisible entities (in Javanese = sing mbau rekso) and people that are superficially influenced by Hinduism in pre modern period (Pegeaud). But this opinion was denied by Nancy J Smith Hefner who stated that the sacred ritual of Tenggerese dukun has strong Hindu impression.

Tenggerese Ritual is not that complex as Javanese one. Tengger Hinduism was built by system that are agreed by the community and arranged officially by dukun or other people know ritual protocols. Dukun inherit  ritual equipments and mantra from their predecessors. Incumbent dukun were from direct descendant from previous dukun or nephew of from father or mother side. Dukun is eligible if he has the following qualities:
1.Having extensive knowledge about Tenggerese tradition especially oral traditions
2.The community should agree to promote him as dukun by a discussion forum and
3.Approved and appointed by related government service.

Tenggerese dukun is appointed through test (mulunen) and witnessed by community from villages in Tengger region on Kasada ceremony held in Poten, The Sea of Sand (caldera), on foot of Mt Bromo. Dukun position is higher than modin in Java-Islam, but lower than pedanda in Bali-Hindu (Widyaprakosa). Dukun inauguration in Kasada ceremony is initiated by long process that should be through by dukun candidates. They should learn and memorize archaic and complex text of Tenggerese mantra.

Tenggerese believe that ancestors spirits reside among them and do not leave this world. The spirits can be invited after certain mantera is read and this mantera is only known by dukun. So dukun in the bridge between common people to ancestor spirits and gods. Therefore dukun can bridge people wishes for protection and save from disaster.

Dukun is an active heir of history of the origin and tradition of Tenggerese, and also treat Tenggerese mantra or japa mantra as  precious and sacred assets. Tenggerese dukun daily activities are filled with rituals, reading mantra  for love, safety, well being, and prosperity to Hong Pukulun, gods, and spirits that guards villages called as dhanyang.

In their activities, dukun read mantra according to the purpose of the rituals. Though Tenggerese dukun admit as part of Javanese society, mantra read by dukun are different than that of Javanese. Mantra read by Tenggerese dukun only have two function: to yield something and to ask for protection, for individual, family, or Tenggerese community. While Javanese dukun mantra usually have 4 functions : to yield something (productive), to protect someone or community (protective), to hurt or kill rival or someone hated (destructive), and to tell fortunes in the future (Koentjaraningrat).

As an oral product, Tenggerese mantra has  been handed down for centuries. The openness of Tenggerese dukun to the ones concern about Tenggerese mantra from outside Tenggerese community yielded rewriting of the mantra by people outside the community. The recording through different time and different writer and from different active heirs causing change. But dukun do not make a fuss about the differences.

Nowadays, there is an official school for Tenggerese dukun. There are currently about 40 dukun and they can speak bahasa Indonesia well. Usually in Kasada only 28 dukun attend.
