Pooja or Poojan is a prayer ritual performed by Hindus to host, honour and worship one or more deities, or to spiritually celebrate an event. Sometimes spelt phonetically as pooja or poojah, it may honour or celebrate the presence of special guests, or their memories after they pass away. The word pooja comes from Sanskrit, and means reverence, honour, homage, adoration, and worship.
In the ancient Indian traditions, a person who had questions or problems first visited a Vedic astrologer for explanations and a better understanding of the situation.. Secondly, he or she went to a priest, to arrange a specific pooja for the blessing from the Gods. Pooja is a spiritual and religious prayer which only a specialized Hindu priest can perform.
Homa is a Sanskrit word that refers to a ritual, wherein an oblation or any religious offering is made into fire.A Homa is sometimes called a "sacrifice ritual" because the fire destroys the offering, but a Homa is more accurately a "votive ritual" The fire is the agent, and the offerings include those that are material and symbolic such as grains, clarified butter, milk, incense and seeds It is rooted in the Vedic religion, and was adopted in ancient times by Buddhism and Jainism.The practice spread from India to Central Asia, East Asia and Southeast Asia.
Yagam literally means "sacrifice, devotion, worship, offering", and refers in Hinduism to any ritual done in front of a sacred fire, often with mantras.Yajna has been a Vedic tradition, described in a layer of Vedic literature called Brahmanas, as well as Yajurveda.The tradition has evolved from offering oblations and libations into sacred fire to symbolic offerings in the presence of sacred fire (Agni). ajna rituals-related texts have been called the Karma-kanda (ritual works) portion of the Vedic literature, in contrast to Jnana-kanda (knowledge) portion contained in the Vedic Upanishads. The proper completion of Yajna-like rituals was the focus of Mimansa school of Hindu philosophy.Yajna have continued to play a central role in a Hindu's rites of passage, such as weddings. Modern major Hindu temple ceremonies, Hindu community celebrations, or monastic initiations may also include Yajna vedic rites, or alternatively be based on agamic rituals.
