The museum is part of Mengwi Temple as place of interest for tourist. The concept of the museum is the preservation of human circle-rites.

For Balinese, there are various rituals since a baby is still in the womb of the mother. The most important ceremony are birth ceremony, otonan ceremony ( every 210 days ), tooth filing ceremony, marriage ceremony, and ngaben ( burial ) ceremony. In this museum the materials and tools of these various ritual are preserved, and step by step to be developed to really represent the variations of the rituals.

That is why this museum is called Manusa Yadnya, literally means Ritual for Human. On 2 May 1980 started to exhibit the ritual from megedong-gedongan ( just born baby ceremony ) until marriage ceremony. In Jun 1981 completed with burial ceremony including Ngaben and mamukur. Ngaben ceremony is not always followed by cremation ritual. Some areas near the mountain and big temple usually do not complete the ritual with cremation.
