A libation is a ritual pouring of a liquid as an offering to a deity or spirit, or in memory of the dead. It was common in many religions of antiquity and continues to be offered in cultures today.
Various substances have been used for libations, most commonly wine or other alcoholic drinks, olive oil, honey, and in India, ghee. The vessels used in the ritual, including the patera, often had a significant form which differentiated them from secular vessels. The libation could be poured onto something of religious significance, such as an altar, or into the earth. On the other hand, one or more libations began most meals and occasions when wine was drunk in Greco-Roman and other ancient societies, mostly using normal cups or jugs.
In East Asia, pouring an offering of rice into a running stream symbolizes the detachment from karma and bad energy.[citation needed]
