Lord Arunachala

Traditional stories tell us that there was an unsettled dispute between Lord Vishnu and Lord Brahma as to who was superior. They sought the help of Lord Siva to judge.
who was really superior; Lord Siva grew into a long flaming light stretching between earth and heaven, and asked them to find root and crown.

Brahma agreeing to reach the crown took the form a swan and flew, and flew to an extending height and could not reach the crown. In his upward flight he caught hold of a flower of Pandavas falling from Siva’s crown and requested the flower to bear a false witness that he collected it from Siva’s crown.

Knowing this Lord Siva cursed Brahma that he would never be worshipped in the temple, and banished Pandavas flower from his adornment. Lord Vishnu took the form of pig and kept digging down to reach Siva’s foot; Siva was really pleased with the humility of Vishnu and took him his heart.

To be blessed with true knowledge, there should be a complete destruction of the ego.
