Gayatri Mantra is the ultimate among mantras.
Gayatri is a Meter, Chandas.
Gayatri is the Mother of All Mantras.
Smritis declare that no mantra will yield results for one who does not chant Gayatri.
Gayatri Mantra was revealed through Sage Viswamitra.
People of three dispositions ,Brahmana, Kshatriya and Vaisya are enjoined to Chant it as a part of Sandhya Vandhana , thrice a day.
Sandhya Vandhana has the following components, apart from routine rituals like Aachamana and Pranayama.
1.Purification of Speech,Body and Mind.
2.Obesiance to water and purification by it.
3.Thanksgiving to Ten planets and ancestors.
4.Atoning one’s impure actions( by speech, body and mind)
5.Worship of The Sun.
7.Worshiping Reality ,Brahman.
8.Realising and offering Worship to Sun as the Visible Reality.
9.Offering the result of Sandhya Vandana to Reality, that is non attachment to action performed.
While worshipping Sun, Sun is requested to be present.
So is Gayatri.
Sun is worshipped as Gayatri and Gayatri as Sun.
As Gayatri is a Meter, Chandas, (Anushtup), the Anushtup is invoked.
Though Gayatri was revealed through Viswamitra,he did not create or invent it.
He, along with other Rishis are invoked; Viswamitra is given pride of place.
Twenty four Rishis are associated with Gayatri,one Rishi for one syllable of Gayatri Mantra,totalling twenty four.
Sinilarly twenty four chandas are referred to , though Gayatri is Anushtup Chandas.
