The Mahānārāyaṇa Upaniṣad is the tenth prapāṭhaka of the Taittirīya Āraṇyaka, in the Kṛṣṇa Yajurveda, Taittirīya śākhā. It is also known as the Yājñikī Upaniṣad.
A student comes to most upaniṣads through their questions. What becomes of a man when he dies, Naciketas asks Yama. By whose will does the mind go out towards its object, asks the Kena. The Mahānārāyaṇa Upaniṣad is not built that way. It puts no question and records no dialogue. It is mantra throughout, and what has carried it for all this time is not its argument but its use.
In use
That use is liturgical. The others are studied, recited, taught and reflected upon as texts. This one is all of that, and it is also the working material of rite after rite, its mantras spoken also by people who are not studying it at all.
It is there in ritual, in the offerings and invocations that open and close a homa. It is there in daily practice: the mantras with which Gāyatrī is invited and then taken leave of at the end of japa belong to this text. It is there before food, in the words spoken over the meal before the first morsel is touched. It is there in the mantras of purification with water and with earth. It is there when a teacher is honoured. It is there in the vows taken at the time of sannyāsa, where its offerings accompany the renunciation of every former claim. And it is there at the end of a life, in the rites that see the body given back and the departed commended onward.
Several of the sūktam-s that students learn early are also part of it. The Nārāyaṇa Sūktam, the Durgā Sūktam, the Medhā Sūktam prayed for intelligence and retention, the series of Gāyatrī-s addressed to Nārasiṃha, Garuḍa, Ṣaṇmukha and others: all of these are Mahānārāyaṇa Upaniṣad.
This is what makes the text unusual among the upaniṣads. It never stopped being used.
The Mṛtyu Nivāraṇa Mantrāḥ
One unbroken sequence within the upaniṣad is given to death. Death is not referred to in these mantras; it is addressed. The mantras say mṛtyo, O Death, again and again, and there is no euphemism anywhere in the group.
The sequence opens by asking for distance:
apaitu mṛtyur amṛtaṃ na āganvaivasvato no abhayaṃ kṛṇotu
May death withdraw, may immortality come to us, may the son of Vivasvān grant us fearlessness.
Then the path itself is named:
paraṃ mṛtyo anu parehi panthāṃ yas te sva itaro devayānātcakṣuṣmate śṛṇvate te bravīmi mā naḥ prajāṃ rīriṣo mota vīrān
Go, O Death, along your own far path. I speak to you as to one who sees and hears: do not harm our children, nor our strong ones.
What follows is not a prayer for escape. It asks for the full span of a life and for nothing to be taken before its time: jyog jīvā jarām aśīmahi, may we live long and reach old age; mā chido mṛtyo mā vadhīḥ, do not sever, do not strike.
The mantra many will already know stands within this group:
tryambakaṃ yajāmahe sugandhiṃ puṣṭi-vardhanamurvārukam iva bandhanān mṛtyor mukṣīya māmṛtāt
The cucumber is not cut from the stalk. It ripens until the stalk lets it go. The mantra asks for that, and then asks not to be severed from immortality. And the whole sequence closes with this:
mṛtyave svāhā mṛtyave svāhā
To Death, svāhā. To Death, svāhā.
Having spoken to death for the length of the sequence, the mantras end by making an offering to it.
At the retreat
From 28 October to 1 November 2026 we gather in Lugano for adhyayanam of the Mahānārāyaṇa Upaniṣad in an immersive setting. We will spend this time learning excerpts of this text and contemplate on the teachings for daily life offered by this Upaniṣad.
We will also recite together the texts our community has been learning through the year, the Śraddhā Sūktam, the Agni Sūktam, the Medhā Sūktam and the Gaṇapati Atharvaśīrṣa, and we will chant the Rudram.
