The Devas and the human beings of the Bhoologa, being unable to withstand the cruelty of Ravana, invocated to Thirumal.
The deity Thirumal, acting as a Pantaram(a religious person hailing from, and serving the ordinary folk), made the Seven Virgins, who were to give birth to seven boys using seven seeds from seven upper worlds (astral planes or lokas).
