Sri Dattatreya Vajra Kavacham Song by Sri Ganapathi Sachchidanda Swamiji

Dattatreya (Sanskrit: दत्तात्रेय, Dattātreya), Dattā or Dattaguru, is a paradigmatic Sannyasi (monk) and one of the lords of yoga, venerated as a Hindu god. In Maharashtra, Goa, Andhra Pradesh, Telangana, Karnataka, Gujarat, and Madhya Pradesh he is a syncretic deity, In Bengal he is known as 'Trinath', avatar of the three Hindu gods Brahma, Vishnu, and Shiva, who are also collectively known as the Trimurti. In other regions, and some versions of texts such as Garuda Purana, Brahma Purana and Sattvata Samhita, he is an avatar of Vishnu only. Several Upanishads are dedicated to him, as are texts of the Vedanta-Yoga tradition in Hinduism. One of the most important texts of Hinduism, namely Avadhuta Gita (literally, "song of the free soul") is attributed to Dattatreya. Over time, Dattatreya has inspired many monastic movements in Shaivism, Vaishnavism, and Shaktism, particularly in the Deccan region of India, south India, Gujarat, Madhya Pradesh, Rajasthan and Himalayan regions where Shiva tradition has been strong. His pursuit of simple life, kindness to all, sharing of his knowledge and the meaning of life during his travels is reverentially mentioned in the poems by Tukaram, a saint-poet of the Bhakti movement.
According to Rigopoulos, in the Nath tradition of Shaivism, Dattatreya is revered as the Adi-Guru (First Teacher) of the Adinath Sampradaya of the Nathas, the first "Lord of Yoga" with mastery of Tantra (techniques), although most traditions and scholars consider Adi Nath to be an epithet of Lord Shiva. According to Mallinson, Dattatreya is not the traditional guru of the Nath Sampradaya but instead was co-opted by the Nath tradition in about the 18th century as a guru, as a part of Vishnu-Shiva syncretism. This is evidenced by the Marathi text Navanathabhaktisara, states Mallinson, wherein there is syncretic fusion of the Nath Sampradaya with the Mahanubhava sect by identifying nine Naths with nine Narayanas.
Dattatreya iconography varies regionally. In Maharashtra, for example, he is typically shown with three heads and six hands, one head each for Brahma, Vishnu and Shiva who represent the Trimurti, the 3 main gods in Hinduism, and one pair of hands holding the symbolic items associated with each of these gods: japamala and water pot of Brahma, conch and discus of Vishnu, trident and drum of Shiva. He is typically dressed as a simple monk, situated in a forest or wilderness suggestive of his renunciation of worldly goods and pursuit of a meditative yogic lifestyle. In paintings and some large carvings, he is surrounded by four dogs and a cow, which symbolise the four Vedas and mother earth who nourishes all living beings. In the temples of southern Maharashtra, Varanasi, and in the Himalayas, he is shown with one head and two hands accompanied by four dogs and a cow.
An annual festival in the Hindu calendar month of Mārgaśīrṣa (November/December) reveres Dattatreya and is known as Datta Jayanti.
In the Puranas, he was born in an Indian hermitage to Anasuya and her husband, the Vedic sage, Atri who is traditionally credited with making the largest contribution to the Rigveda. It is said that they lived in Mahur, Nanded District, Maharashtra. Another states that his father lived in the western Deccan region. A third claims he was born in the jungles of Kashmir near the sacred Amarnath Temple. A fourth legend states he was born along with his brothers Durvasa and Chandra, to an unwed mother named Anusuya, In a fifth myth, sage Atri was very old when young Anusuya married him and they sought the help of the trimurti gods for a child. As the trinity were pleased with them for having brought light and knowledge to the world, instantly granted the boon, which led Dattatreya to be born with characteristics of all three.
While his origins are unclear, stories about his life are clearer. He is described in the Mahabharata as an exceptional Rishi (sage) with extraordinary insights and knowledge, who is adored and raised to a Guru and an Avatar of Vishnu in the Puranas. Dattatreya is stated in these texts to having renounced the world and leaving his home at an early age to lead a monastic life. One myth claims he meditated immersed in water for a long time, another has him wandering from childhood and the young Dattatreya footprints have been preserved on a lonely peak at Girnar (Junagadh, Gujarat).[20] and Dattatray make a tapa for 12000 years over there. The Tripura-rahasya refers to the disciple Parasurama finding Dattatreya meditating on Gandhamadana mountain, Near Rameswaram, Tamil Nadu.
Dattatreya is said to have his lunch daily by taking alms at a holy place Pithapuram, Andhra Pradesh, where he was born as Sripada Sri Vallabha (his first avatar).
The young Dattatreya is famous in the Hindu texts as the one who started with nothing and without teachers, yet reached self-awareness by observing nature during his Sannyasi wanderings, and treating these natural observations as his twenty four teachers. ॐ
