Toraja religion, Aluk To Dolo, is documented substantially through its funeral practice, which is also the reason the tradition has drawn sustained outside attention. Toraja funerals, which can be delayed for months or years while a family assembles the resources for an elaborate ceremony including large scale buffalo sacrifice, are held to determine the fate of the deceased's spirit in the journey to Puang Matua, the creator, and to the deata, deities and spirits of the upper and lower worlds. Ethnographers working in the Sulawesi highlands from the Dutch colonial period onward documented this sequence in detail, and the funerals themselves became, over the twentieth century, a significant point of contact between Toraja communities and outside visitors, contributing to the highlands becoming one of Indonesia's more internationally known destinations for observing indigenous ritual.
Indonesia's constitutional requirement that citizens register under one of a limited set of officially recognised religions placed Aluk To Dolo practitioners in a difficult position, since the indigenous religion itself was not on the recognised list. In 1969, Aluk To Dolo was granted legal status as a form of Hinduism, a classification many Toraja practitioners accepted pragmatically as the available route to state recognition of their existing practice rather than as an assertion that Aluk To Dolo originated from or converged with Hinduism as practised in India or Bali. That administrative history is now part of how the tradition's institutional standing is documented, alongside the older ethnographic record of the funeral rites themselves.
