The five are listed in the Taittirīya Āraṇyaka and codified in the Dharma Śāstras and Gṛhya Sūtras (notably the Manu Smṛti 3.69–71). They exist, the texts say, partly to atone for the five sūnā - the five places of unavoidable harm in every home (the hearth, the grindstone, the broom, the mortar-and-pestle, and the water-pot) - so that the householder, who cannot live without some injury to other creatures, balances it daily with acts of giving and reverence.
№ 1Brahma-yajña - the sacrifice to Brahman / the sages
also called Ṛṣi-yajña or Veda-yajña
What it is - The daily study (svādhyāya) and recitation of the Veda, and its teaching onward to others. By keeping the sacred knowledge alive in one’s own mouth and passing it on, the householder honours the ṛṣis who first heard and preserved it.
How it is kept simply today - Recite a portion of scripture each day - the Gāyatrī, a sūkta, a few verses of the Gītā or an Upaniṣad; read, learn, and share what you understand with family or students. Any sincere svādhyāya keeps this yajña.
The debt it repays - Repays the ṛṣi-ṛṇa - the debt to the sages, who gave us the knowledge by which we live and worship.
№ 2Deva-yajña - the sacrifice to the gods
kept as homa / agnihotra
What it is - An offering to the devas through the sacred fire - the agnihotra and the daily homa, in which oblations of ghee and grain are placed in Agni, the fire being the mouth of the gods. It acknowledges that the powers of nature sustain all life.
How it is kept simply today - Where a fire is kept, a small daily homa or aupāsana; where it is not, a lamp (dīpa), incense and naivedya offered before the household deities, with a short prayer, fulfils the spirit of deva-yajña.
The debt it repays - Repays the deva-ṛṇa - the debt to the gods, the cosmic powers (sun, rain, fire, air) that uphold the order in which we live.
№ 3Pitṛ-yajña - the sacrifice to the ancestors
kept as tarpaṇa
What it is - The daily offering of water (and, on the appointed days, food) to the forefathers - tarpaṇa, the libation that satisfies the pitṛs. It remembers that one’s very body and lineage are an inheritance from those who came before.
How it is kept simply today - A simple daily tarpaṇa of water offered to the ancestors; the fuller śrāddha rites kept at the right tithis and during Pitṛ Pakṣa. Caring for living elders is held to be of a piece with this duty.
The debt it repays - Repays the pitṛ-ṛṇa - the debt to the ancestors, for the body, the family and the continuity of life they handed down.
№ 4Bhūta-yajña - the sacrifice to all beings
also called Vaiśvadeva or Bali
What it is - Food offered to all creatures - the bali, portions of the cooked meal set apart for animals, birds, insects and the unseen beings before the family eats. It recognises a duty of care to every living thing that shares the earth.
How it is kept simply today - Set aside a little food for a cow, a dog, the birds and the ants; keep the older custom of feeding animals before one’s own meal. Any daily act of feeding the creatures around the home keeps bhūta-yajña.
The debt it repays - A duty of compassion to all beings (bhūtas); the householder repays the shelter and sustenance the living world provides by feeding the creatures that depend on it.
№ 5Manuṣya-yajña - the sacrifice to fellow humans
also called Nṛ-yajña or Atithi-yajña
What it is - Hospitality to the guest - atithi, the one who arrives unannounced - and the feeding of the hungry. The tradition holds the guest to be a form of the Divine (atithi devo bhava), to be received and fed before oneself.
How it is kept simply today - Welcome and feed whoever comes to the door; give food to the hungry; share a meal. Annadāna - the giving of food - is the everyday form of manuṣya-yajña and the most praised of charities.
The debt it repays - A duty owed to fellow human beings; the householder discharges it by hospitality and by feeding those in need, so that no guest or hungry person is turned away.
Deva-ṛṇa - the debt to the gods
Discharged through Deva-yajña (homa / worship). We owe the gods - the powers of nature that sustain us - and we repay them with offerings of fire and devotion.
Ṛṣi-ṛṇa - the debt to the sages
Discharged through Brahma-yajña (study and teaching of the Veda). We owe the ṛṣis who preserved sacred knowledge, and we repay them by learning it, keeping it alive, and passing it on.
Pitṛ-ṛṇa - the debt to the ancestors
Discharged through Pitṛ-yajña (tarpaṇa / śrāddha) and, in the classical view, by raising a virtuous family that continues the line. We owe our forefathers for our very birth, and we repay them with remembrance and offerings.
