Yajna

Yajna (IAST: yajña) 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).

Yajna 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.

Etymology

The word yajna (Sanskrit: यज्ञ; yajña or yajJa) appears in the early Vedic literature, composed in 2nd millennium BCE. In Rigveda, Yajurveda and others, it means "worship, devotion to anything, prayer and praise, an act of worship or devotion, a form of offering or oblation, and sacrifice". In post-Vedic literature, the term meant any form of rite, ceremony or devotion with an actual or symbolic offering or effort.

Shiva

Shiva (/ˈʃivə/; Sanskrit: Śiva, meaning "The Auspicious One", also known as Mahadeva ("Great God"), is one of the three major deities of Hinduism. Shiva is in the form of Vishnu and Brahma yet one with them. He is Anant, one who is neither found born nor found dead. He is the Parabrahman within Shaivism, one of the three most influential denominations in contemporary Hinduism. He is one of the five primary forms of God in the Smarta Tradition, and "the Transformer".

At the highest level, Shiva is regarded as limitless, transcendent, unchanging and formless. Shiva also has many benevolent and fearsome forms. In benevolent aspects, he is depicted as an omniscient Yogi who lives an ascetic life on Mount Kailash, as well as a householder with wife Parvati and his two children, Ganesha and Kartikeya, and in fierce aspects, he is often depicted slaying demons. Shiva is also regarded as the patron god of yoga and arts.

The main iconographical attributes of Shiva are the third eye on his forehead, the snake Vasuki around his neck, the adorning crescent moon, the holy river Ganga flowing from his matted hair, the trishula as his weapon and the damaru as his musical instrument. Shiva is usually worshiped in the aniconic form of Lingam. The worship of Shiva is a pan-Hindu tradition, practiced widely across all of India, Nepal and Sri Lanka.
