Pūjā or Poojan is a prayer ritual performed by Hindus to host, honor and worship one or more deities, or to spiritually celebrate an event. Sometimes spelt phonetically as pooja or poojah, it may honor or celebrate the presence of special guest(s), or their memories after they pass away. The word pūjā (पूजा) comes from Sanskrit, and means reverence, honour, homage, adoration, and worship. Puja rituals are also held by Buddhists, Jains and Sikhs.
