The word maga refers to a dynasty of priests of whom Jarasabdha was a progenitor. In ancient Iran, the hereditary priestly caste was called the Magi. Bhavisya Purana states that Jarasabdha was born in the family line of vira-aditya, "the powerful Aditya" (sun-god). The Vedic scriptures list twelve Adityas (sons of Aditi, the mother of the demigods). They are the twelve spokes of the kala-cakra, the wheel of time. Chandogya Upanisad 3. 8. 1 proclaims Varuna the chief Aditya.
Zarathushtra uses Maga for the "Fellowship" he founded through his existential philosophy  and "Magavan" for every member of the "Magnanimity." The two words -- Maga and Magavan -- are mentioned for eight times in the Gathas (Maga: Songs 2:11, 11:14, 16:11, 16:16, 17.7 (twice), and Magavan: 6:7, 16:15). Zarathushtra calls his Maga as "maz, great" in two Gathic stanzas --  Maz Maga, the Great Magnanimity, Great Fellowship (2:11 and 11:14).
