In Hinduism, Yajña or Yagna (Sanskrit: यज्ञ, lit.'act of devotion, worship, offering in fire', IAST: yajña), also known as Havana in modern contexts,[1] is a ritual done in front of a sacred fire (agni), often with mantras.[2] Yajna has been a Vedic tradition, described in a layer of Vedic literature called the Brahmanas, as well as in the Yajurveda.[3] The tradition has evolved from offering oblations and libations into sacred fire to symbolic offerings in the presence of said sacred fire.[2]

Yajna rituals-related texts have been called the Karma-kanda (ritual works) portion of the Vedic literature, in contrast to the Jnana-kanda (knowledge) portion found in the Vedic Upanishads. The proper completion of Yajna-like rituals was the focus of Mimansa school of Hindu philosophy.[4] Yajna have continued to play a central role in Hindu rites of passage, such as weddings.[5] Modern major Hindu temple ceremonies, Hindu community celebrations, or monastic initiations may also include Vedic Yajna rites, or alternatively be based on Agamic rituals.

Etymology

The word yajna (Sanskrit: यज्ञ, romanized: yajña) has its root in the Sanskrit yaj meaning 'to worship, adore, honour, revere' and appears in the early Vedic literature, composed in 2nd millennium BCE.[6][7] In Rigveda, Yajurveda (itself a derivative of this root) 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".[6] In post-Vedic literature, the term meant any form of rite, ceremony or devotion with an actual or symbolic offering or effort.[6]

A yajna included major ceremonial devotions, with or without a sacred fire, sometimes with feasts and community events. It has, states Nigal, a threefold meaning of worship of the deities (devapujana), unity (sangatikarana) and charity (dána).[8]

The Sanskrit word is related to the Avestan term yasna of Zoroastrianism. Unlike the Vedic yajna, however, the Yasna is the name of a specific religious service, not a class of rituals, and they have "to do with water rather than fire".[9][10] The Sanskrit word is further related to Ancient Greek ἅζομαι (házomai), "to revere", deriving from the Proto-Indo-European root *Hyeh₂ǵ- ("to worship").

History

Yajna has been a part of an individual or social ritual since Vedic times. When the ritual fire – the divine Agni, the god of fire and the messenger of gods – was deployed in a Yajna, mantras were chanted.[7] The hymns and songs sung and oblations offered into the fire were a form of hospitality towards the Vedic gods. The offerings were believed to be carried by Agni to the gods; the gods in return were expected to grant boons and benedictions, and thus the ritual served as a means of spiritual exchange between gods and human beings.[7][11] The Vedangas, or auxiliary sciences attached to the Vedic literature, define Yajna as follows:

Apastamba Yajna Paribhasa-sutras 1.1, Translator: M Dhavamony[12][13]

In the Upanishadic times, or after 500 BCE, states Sikora, the meaning of the term Yajna evolved from "ritual sacrifice" performed around fires by priests, to any "personal attitude and action or knowledge" that required devotion and dedication.[7] The oldest Vedic Upanishads, such as the Chandogya Upanishad (~700 BCE) in Chapter 8, for example state,[14]

अथ यद्यज्ञ इत्याचक्षते ब्रह्मचर्यमेव
 तद्ब्रह्मचर्येण ह्येव यो ज्ञाता तं
विन्दतेऽथ यदिष्टमित्याचक्षते ब्रह्मचर्यमेव
 तद्ब्रह्मचर्येण ह्येवेष्ट्वात्मानमनुविन्दते ॥ १ ॥

What is commonly called Yajna is really the chaste life of the student of sacred knowledge,
  for only through the chaste life of a student does he who is a knower find that,
What is commonly called Istam (sacrificial offering) is really the chaste life of the student of sacred knowledge,
  for only having searched with chaste life of a student does one find Atman (Soul, Self) || 1 ||

Chandogya Upanishad 8.5.1 [14][15]

The later Vedic Upanishads expand the idea further by suggesting that Yoga is a form of Yajna (devotion, sacrifice).[15] The Shvetashvatara Upanishad in verse 1.5.14, for example, uses the analogy of Yajna materials to explain the means to see one's soul and God, with inner rituals and without external rituals.[15][16] It states, "by making one's own body as the lower friction sticks, the syllable Om as the upper friction sticks, then practicing the friction of meditation, one may see the Deva who is hidden, as it were".[16]

Changing nature of Vedic offerings

The nature of Vedic sacrifice and rituals evolved over time, with major changes during the 1st millennium BCE, changes that influenced concepts later adopted by other traditions such as Buddhism.[17] Early Vedic period offerings involved animal sacrifice, but the rituals were progressively reinterpreted over time, substituting the offerings and making it non-violent or symbolic, with the superiority of knowledge and celebration of sound of mantra replacing the physical offerings. Ultimately, the external rituals were reformulated and replaced with "internal oblations performed within the human body".[17] These ideas of substitution, evolution from external actions (karma-kanda) to internal knowledge (jñana-kanda), were highlighted in many rituals-related sutras, as well as specialized texts such as the Brihadaranyaka Upanishad (~800 BCE), Chandogya Upanishad, Kaushitaki Upanishad and Pranagnihotra Upanishad.[18][19]

The Vedic text Satapatha Brahmana defines a sacrifice as an act of abandonment of something one holds of value, such as oblations offered to god and dakshina (fees, gifts) offered during the yajna.[17] For gifts and fees, the text recommends giving cows, clothing, horses or gold.[17] The oblations recommended are cow milk, ghee (clarified butter), seeds, grains, flowers, water and food cakes (rice cake, for example). Similar recommendations are repeated in other texts, such as in the Taittiriya Shakha 2.10 of the Krishna Yajurveda).[20]

Tadeusz Skorupski states that these sacrifices were a part of ritual way of life, and considered to have inherent efficacy, where doing these sacrifices yielded repayment and results without the priests or gods getting involved.[17] These Vedic ideas, adds Skorupski, influenced "the formulation of Buddhist theory of generosity".[17] Buddhist ideas went further, criticizing "the Brahmins for their decadence and failure to live in conformity with the Brahmanic legacy of the ancient Brahmins", who claimed the Vedic ancients "lived in self restraint, were ascetics, had no cattle, no gold, and no wealth".[21] The Buddha sought return to more ancient values, states Tadeusz Skorupski, where the Vedic sages "had study as their grain and wealth, guarded the holy life as their treasure, praised morality, austerity and nonviolence; they performed sacrifices consisting of rice, barley and oil, but they did not kill the cows".[21]
