Puja is the primary form of Hindu worship, a ritual through which devotees honor a deity with offerings, prayers, and expressions of devotion. A traditional puja includes: invocation (Avahana), offering a seat (Asana), washing feet (Padya), offering water (Arghya), bathing the deity (Abhishekam), clothing (Vastra), sacred thread (Yajnopavita), sandalwood paste (Gandha), flowers (Pushpa), incense (Dhupa), lamp (Deepa), food offering (Naivedya), and circumambulation (Pradakshina). Puja can be performed at home (griha puja), in temples (mandir puja), or at special ceremonies. The complexity ranges from simple daily prayers with a lamp and flowers to elaborate multi-day rituals with Vedic chanting by priests.
