According to a legend in Mahabharata – आरण्यकपर्व – chapter 104, the Vindhya ( विन्ध्यः ) mountain, being jealous of the mount Meru (Himālaya) demanded that the sun should revolve round him also, as sun was revolving round the Meru, which the sun declined to do.
Unhappy with the sun, the Vindhya began to rise higher and higher so as to obstruct the path of the sun and moon.
Rishi Agastya on the request of devata’s approcahed near the mountain and requested that by bending down he would give him an easy passage to the south, and that he would retain the same position till his return.and said :
This Vindhya agreed to do (because he regarded Agastya as his teacher); but Agastya never returned from the south, and Vindhya never attained the height of Meru (Himālaya)
