The Gāyatrī Mantra — Origins in the Classics and Its Place in Jyotiṣa

The Gāyatrī is a single verse of the Ṛgveda (3.62.10), addressed to Savitṛ, the divine Sun as the one who impels. Over the following centuries the Yajurveda joined the vyāhṛtis to it, the Upaniṣads made it the image of all creation, and the Smṛtis made it the heart of upanayana and the daily sandhyā. This article traces that journey text by text, then shows why the Gāyatrī matters to a Jyotiṣī. An index at the end gives the source for each point.

1. The mantra

ओं भूर्भुवः स्वः ।
तत्सवितुर्वरेण्यं भर्गो देवस्य धीमहि ।
धियो यो नः प्रचोदयात् ॥

oṃ bhūr bhuvaḥ svaḥ |
tat savitur vareṇyaṃ bhargo devasya dhīmahi |
dhiyo yo naḥ pracodayāt ||

"We meditate on that most excellent radiance of the divine Savitṛ. May he impel our minds."

2. Origin in the Ṛgveda

The verse is Ṛgveda 3.62.10, in the third maṇḍala, the "family book" of the Viśvāmitras. Every Vedic mantra has three marks: its seer (ṛṣi), its deity (devatā) and its metre (chandas).

• Ṛṣi: Viśvāmitra Gāthina. Born a kṣatriya king, Viśvāmitra became a brahmarṣi through tapas. The tradition holds that he "saw" this verse, and it has carried his name ever since. His son Madhucchandas, seer of the Sarasvatī mantra (Ṛgveda 1.3.10), was also a master of the Gāyatrī metre.
• Devatā: Savitṛ. Savitṛ is the Sun as impeller (√sū): the power that rouses beings at dawn and sets them moving. Commentators such as Sāyaṇa distinguish him from Sūrya, the visible disc. The verse is therefore properly called the Sāvitrī.
• Chandas: Gāyatrī. The metre has three feet (pādas) of eight syllables each, 24 in all. Recited as written, the verse has 23. The tradition restores the full 24 by reading vareṇyam as vareṇiyam. Because the metre is so perfectly embodied here, the verse took the metre's name and became the Gāyatrī.

3. Through the other Vedas

The verse travels from the Ṛgveda into the other Saṃhitās:

• Yajurveda. The Vājasaneyi Saṃhitā (Śukla Yajurveda) repeats the verse several times, including 3.35, 22.9 and 30.2. At 36.3 it appears with the three great vyāhṛtis prefixed: bhūr bhuvaḥ svaḥ tat savitur vareṇyaṃ… This is the earliest source of the form chanted today. The Taittirīya Saṃhitā (Kṛṣṇa Yajurveda) also uses it in its rites.
• Sāmaveda. The verse is set to melody in the Uttarārcika, so it is sung as well as recited.

The vyāhṛtis place the meditation in all three worlds, earth, mid-space and heaven, before the verse turns to Savitṛ who shines beyond them. Oṃ, distilled from those three utterances (Chāndogya Upaniṣad 2.23.3), comes before all.

4. In the Upaniṣads

Chāndogya Upaniṣad 3.12 makes the Gāyatrī the whole of creation:

गायत्री वा इदं सर्वं भूतं यदिदं किं च । वाग्वै गायत्री । वाग्वा इदं सर्वं भूतं गायति च त्रायते च ।

gāyatrī vā idaṃ sarvaṃ bhūtaṃ yad idaṃ kiṃ ca | vāg vai gāyatrī | vāg vā idaṃ sarvaṃ bhūtaṃ gāyati ca trāyate ca |

"The Gāyatrī is all this, whatever exists. Speech is the Gāyatrī, for speech sings (gāyati) and protects (trāyate) all that exists." Here is the classic explanation of the name: gāyantam trāyate, "she protects the one who sings her." The same section calls the Gāyatrī four-footed and six-fold, and quotes the Puruṣa Sūkta: one foot of it is all beings, three feet are the immortal in heaven.

Bṛhadāraṇyaka Upaniṣad 5.14 counts the syllables of each foot and finds the universe in them:

The fourth foot is not spoken; it is the Sun itself, shining above all that the first three contain. The Upaniṣad also explains the name: the Gāyatrī protected (tatre) the gayas, and gayas are the vital breaths (prāṇas) (5.14.4). Knowing the Gāyatrī, it says, a person gains all three worlds, all knowledge and all life.

5. In Smṛti and ritual

Vedamātā, mother of the Vedas. The Atharvaveda (19.71.1) praises her as varadā vedamātā, "the boon-giving mother of the Vedas."

Manusmṛti, chapter 2, gives the Gāyatrī its place in daily life:

• 2.76–78: Prajāpati milked the sounds A, U and M and the three vyāhṛtis from the three Vedas, and milked one foot of the Sāvitrī from each Veda.
• 2.79: one who repeats Oṃ, the vyāhṛtis and the Sāvitrī a thousand times outside the village is freed within a month even from great sin, "as a snake from its slough."
• 2.81: "The three imperishable great vyāhṛtis, preceded by Oṃ, and the three-footed Sāvitrī: know these as the mouth of the Veda."
• 2.101: at dawn one stands reciting the Sāvitrī until the Sun is seen; at dusk one sits reciting it until the stars appear.

Upanayana. The sacred-thread ceremony is, at its core, the giving of the Gāyatrī. The Āśvalāyana Gṛhya Sūtra (1.21) describes the teacher passing on the Sāvitrī first foot by foot, then half by half, then whole. The tradition holds that this mantra above all is given by the father to the son, carrying the lineage (vaṃśa) forward.

Sandhyāvandana. The Gāyatrī is recited at the three junctions of the day. Tradition sees the one Devī in three forms:

6. The Gāyatrī in Jyotiṣa

Jyotiṣa is the "eye of the Veda" (vedacakṣu), and its central light is the Sun. A mantra to Savitṛ therefore sits at the heart of the science.

From the tradition

1. The Sun is the soul. Savitṛ is the Sun, and in Jyotiṣa the Sun is the natural ātmakāraka, significator of the soul. Parāśara makes the Sun a kāraka of the 1st, 9th and 10th houses: the self, dharma and the father, and one's work in the world. Reciting the Gāyatrī is a daily strengthening of the Sun's significations.
2. The mantra of the father. The Gāyatrī is given at upanayana and passed from father to son. That places it in the 9th house: father, guru, dharma and lineage, where the Sun is kāraka.

Interpretation, not a classical rule

• Dhī and the 5th house. The prayer asks for one thing: that Savitṛ impel our dhiyaḥ, our intellects. The 5th house governs buddhi and mantra, and the 5th and 9th, both Jupiter's houses, form a trine of wisdom and dharma. The Gāyatrī joins them.
• Protection at the junctions. The Gāyatrī is recited at the sandhis of the day, and the Chāndogya says she protects (trāyate). In a chart, sandhis are the points of greatest weakness: gaṇḍānta, bhāva-sandhi, and planets at the very edge of a sign. A native with such placements, or with an afflicted Sun (debilitated, eclipsed by the nodes, or in a duṣṭhāna), has strong reason to keep the Gāyatrī at the three sandhyās.
• The three times as Brahmā, Viṣṇu and Śiva. Dawn creates, midday sustains, dusk dissolves. The same three powers run through the chart as the trines (dharma), the kendras (action and sustenance) and the duṣṭhānas (dissolution).
