According to Hindu mythology, Lord Dattatreya is believed to be the
combined avatar (incarnation) of the Hindu trinity (Brahma, Vishnu and
Shiva). Sage Atri prayed to the Hindu trinity, and when they were
pleased with his penance, they appeared before him and offered to grant
him a boon. Sage Atri asked for an offspring that would have their
benevolent qualities. Thus, Lord Dattatreya was born.Lord Dattatreya is depicted as having three heads, symbolizing the past, present, and future. His three heads also symbolize the three states of consciousness. He is pictured with four dogs around him, which represent the four Vedas and his mastery over them. Lord Dattatreya is considered the teacher of all gods. He dispels all evil influences.
