Once Vindhyachal mountain told the Sun that he always circles around Sumeru, and asked him if maybe he could sometime circle around him as well. The Sun said it was not possible to do so.
This angered Vindhy and he started growing in size. He grew so large that he started blocking the Sun. Livestock on the earth started suffering due to lack of sunlight.
All the Gods approached the great sage Agastya to help them stop Vindhya’s growth and allow sunlight to reach the earth.
Agastya rishi went to Vindhyachal and requested him to give way for him to travel south. Vindhya bowed and gave way to the great sage. Rishi Agastya asked him to wait for him till he came back.
The great sage stayed in the south and never returned thus keeping Vindhyachal bowed forever in the wait for his return.
