According to the Linga Purana, Mercury is the
son of the Moon by his wife Rohini.
in the Vishnu Purana, Brahma Purana, Devi Bhagvata Bhagwat
Purana, Harivansha Purana, Padma Purana and Vayu Purana a
story is told of the seduction of Brahaspati's (Jupiter's)
wife Tara by the Moon - and Buddha is born from her. He is
called Saumya, that is, "Son of Soma [Moon]." From
Buddha springs the lunar race. The Moon, being his father,
is friendly toward him, but Mercury knows that he is son of
the wife of Jupiter and so he is in conflict with the Moon,
who seduced his mother.
