Bhaga is one of the twelve Ādityas (solar deities of the Vedas) born to Kaśyapa Prajāpati and his wife Aditi.
According to another view he is classed among the eleven Rudras.
He is said to be the lord of the month Puṣya (January-February). It is quite likely that the twelve Ādityas are the twelve aspects of the sun spread over the twelve months and the aspect connected with the month Puṣya is named Bhaga.
There was one Bhaga in the sacrificial assembly of Dakṣa Prajāpati. He too like others was subjected to the wrath of Vīrabhadra, the terrible emissary of Śiva, and lost his eyes.
The word bhaga represents the group of six guṇas or blessed qualities: aiśvarya (lordship), dharma (righteousness), yaśas (renown), śrī (splendour), jñāna (know-ledge) and vairāgya (detachment). One who possesses these in abundance is ‘Bhagavān.’ The term is generally applied to God; and even to sages and prophets. When applied to a goddess it becomes ‘Bhagavatī.’
Sometimes these six guṇas are listed in a slightly different way: jñāna, aiśvarya, śakti (ability), bala (strength), vīrya (viri-lity) and tejas (splendour). They are considered as the material or instruments of śuddhasṛṣṭi or pure creation. They also play a part in the manifestation of vyūhas or emanations from God Vāsudeva viz., Saṅkarṣaṇa, Pradyumna and Aniruddha.
