A pujari conducts puja, the ritual worship of a deity's consecrated image, murti, at a Hindu temple, a role encompassing the daily cycle of ritual care the deity is traditionally understood to require: waking the deity in the morning, ceremonial bathing, dressing and offerings of food, flowers and incense at set times through the day, and aarti, the ritual waving of lit lamps before the image, performed at specific points in the temple's daily schedule and drawing lay worshippers to attend. The specific procedures a pujari follows, agama, are governed by detailed ritual manuals particular to the deity, the specific temple tradition, and the regional and sectarian conventions involved, requiring training a pujari typically receives through extended apprenticeship, formal training at a dedicated institution, or, in many temples, inheritance of the role within a family long associated with a specific temple.
Temple administration in much of modern India has increasingly moved toward formal government or trust-based oversight of major temples, particularly in South India, a shift that has in some cases altered the pujari's traditional employment relationship from a hereditary, largely autonomous position to that of a salaried employee of a temple trust or state religious endowments board, a change that has drawn both administrative benefits in financial transparency and, from some traditional priestly families, concern about the erosion of hereditary priestly rights and authority over temple ritual practice.
