Abhisheka or Abhishekam (Devanagari: अभिषेक abhiṣeka) is a Sanskrit term akin to puja, yagya and arati that denotes: a devotional activity; an enacted prayer,rite of passage and/or religious rite. Within this range of senses, abhiṣeka is common to all Dharmic faiths such as Hinduism, Buddhism and Jainism.
Abhisheka, also called Abhishekam, is conducted by priests, by pouring libations on the image of the deity being worshipped, amidst the chanting of mantras. Usually, offerings such as milk, yogurt, ghee, honey, Panchaamrutam, sesame oil, rosewater, sandalwood paste may be poured among other offerings depending on the type of abhishekam being performed. This rite is routinely performed in some Hindu and Jain temples. "Rudraabhisheka" (रुद्राभिषेक) (Abhisheka of Rudra) is performed on Shiva lingams.
In the Indo-Tibetan Buddhist tradition, an abhisheka can be a method for performing esoteric transmission, a way to offer blessings of a lineage to participants, or it can be an empowerment to begin a particular meditation practice.
