What the verse says
In plain translation: "We meditate upon that excellent radiance of the god Savitṛ; may he inspire our thoughts." The three syllables bhūr bhuvaḥ svaḥ that precede the verse proper are not part of the original Ṛg Vedic verse — they are the three vyāhṛtis ("utterances"), drawn from the Taittirīya Āraṇyaka, prefixed in later ritual use to invoke the three worlds (earth, atmosphere, heaven) before the meditation begins.
When and how it is used
The Gāyatrī is central to sandhyāvandana, the daily twilight-worship ritual traditionally performed at dawn, noon, and dusk following the Upanayana (sacred thread) ceremony. It is also widely used independently as a japa (repetition) mantra, and recited before Vedic study.

Across the Vedic corpus
The verse's oldest attestation is Ṛg Veda 3.62.10, part of a hymn (sūkta) attributed to the sage Viśvāmitra. It recurs in the Yajur Veda (Vājasaneyi Saṃhitā 36.3 and Taittirīya Saṃhitā 4.1.11) and in the Sāma Veda, with only minor textual variants across recensions — a rare case of a single verse crossing all three of the older Vedas largely intact.
The Viśvāmitra connection
Viśvāmitra's association with this verse is significant within the tradition's own narrative: he is remembered as a kṣatriya (warrior) who became a brahmarṣi (sage of brahminical rank) through spiritual practice — making the Gāyatrī, in traditional memory, a verse revealed to someone who was not born into the priestly class.
How later tradition read the verse
The Gāyatrī's exact meaning has been elaborated differently across schools. Vedāntic commentary tends to read bhargaḥ ("radiance") as pointing beyond the physical sun to the light of consciousness itself — the sun as a visible symbol for Brahman, the light by which all seeing happens. This reading connects the Gāyatrī to the broader Upaniṣadic move from external ritual toward internal contemplation.
The Gāyatrī's structural influence extends well beyond this one verse: because it demonstrated that a deity could be addressed in this compact three-line form, later tradition composed parallel "Gāyatrī" mantras to other deities on the same metrical model — see the Gāyatrī Family category for these later, structurally-modeled compositions, which should not be mistaken for equally ancient.
