Agastya

Agastya (अगस्त्य in devanagari, pronounced /ə gəs tyə/) was a Vedic sage or rishi. Agastya and his clan are also credited^[who?] to have "authored" many mantras of the Rig Veda, the earliest and most revered Hindu scripture, in the sense of first having the mantras revealed in his mind by the Supreme Brahman. Agastya is also the author of Agastya Samhita[ref: Dharma Bharathi]. In some reckonings, Agastya is the greatest of the Seven Sages or Saptarshis. The word is also written as Agasti. A-ga means a mountain, Asti, thrower. Also a name of Lord Shiva. Agastya the Rishi, was born of both Gods, Mitra and Varuna, from Urvashi. Agastya is also the Indian astronomical name of the star of Canopus, is said to be the 'cleanser of waters', since its rising coincides with the calming of the waters of the Indian Ocean. Another reference is in the Mahabharata in Sauptikaparva as the teacher of Guru Drona, who gave Drona, the greatest of weapons, Brahmastra (used by both Arjuna and Ashwatthama at the end of the war).
