Vidhyachal obstructs the path of Surya
Vindhyachala mountain was filled with inferiority complex and started waiting for an opportunity when he could prove his superiority to Meru mountain. He thought--' Perhaps Narada was right for even Lord Surya has great respect for Meru's might and this is the reason why he circumambulates my adversary. If I am able to beat Meru in height then may be Lord Surya would start circumambulating me and this way I shall prove my superiority to Meru.'
Now, Vindhyachala started increasing his height and in a short time its peaks became invisible. The fallout of this amazing incident proved to be quite catastrophic for the world because even Lord Surya was left stranded at a particular point in the horizon. As a result, one part of the earth became too hot for any life to exist. Similarly, the other half of the earth became unbearably cold. The time became still and everything went haywire in the world.
All the deities became extremely worried and went to Lord Brahma to seek his help. Lord Brahma advised them to go to Kashi and seek help from sage Agastya. Deities were pleased at their good fortune of getting a chance to visit Kashi. Deities, after reaching Kashi paid a visit to 'Manikarnika teertha' and took their bath. Subsequently, they went to Vishwanatha temple and worshipped Lord Vishwanatha. At last, they reached the hermitage of Agastya where he was busy worshipping a self made Shivalinga. The entire hermitage was crowded with young pupils of Agastya. After the pleasantries having been exchanged, sage Agastaya asked the deities about the purpose of their visit.
Agastya orders Vindhya to diminish its size
When Agastya learnt of the problem created by Vindhyachala, he agreed to help the deities despite fully aware of the fact that once he left Kashi it would not be possible for him to see his dearest Kashi once again at least in his present birth. Before leaving for Vindhyachala, he sought permission from Lord Bhairava. He then reached the place where Vindhyachala had obstructed the path of Surya. Lopamudra, his wife accompanied him.
When Vindhyachala found Agastya starring angrily at him he became scarred and immediately minimized his size. Sage Agastya was pleased that his objective had been achieved without making any effort but he knew quite well that once he left the place Vindhyachala would regain his mammoth size. So he decided to do something so that Vindhyachala could not obstruct the path of Surya. He worked out a plan according to which he instructed Vindhyachala to wait for him until he returned after accomplishing his pilgrimage. Vindhyachala agreed assuming that Agastya would return in a short time.
Vindhyachala thanked his good fortune of escaping Agastya's wrath, which could otherwise have threatened his very existence. Sage Agastya then went away never to return and Vindhyachala kept on waiting for his arrival. This way, the path being cleared, Surya was once again able to move freely on its orbit without any problem and as a result normalcy returned to the world.
On the other hand, Agastya who was not at all happy leaving his dearest Kashi was desperate to get there back as soon as possible. But, he knew that his wish was going to remain unfulfilled. While wandering about, he reached Kolapura where he worshipped goddess Mahalaxmi. When goddess Mahalaxmi appeared, he asked her whether he would ever be able to reach Kashi in his present life. Goddess Mahalaxmi replied--' Your wishes will be fulfilled in the coming nineteenth dwapara yuga, when you would incarnate as Vyas and would contribute a great deal in the propagation of the Vedas and Puranas. There is a sacrosanct place of Kartikeya not very far from here. Go there and pay your obeisance to Lord Kartikeya and he would unravel the mysterious aspects of Kashi to you.'
Sage Agastya and his wife Lopamudra then went to the mountain called Sri Shaila, where Kartikeya lived at that time.
