The effulgence, which had been divided by lord Shiva into the Ocean resulted into the manifestation of a small child. This incident happened at the place where river Ganges submerged into the ocean and which is also known as Gangasagar now a days.
The child was crying so ferociously that an environment of fear was created everywhere. The deities and the sages went to lord Brahma to satisfy their curiously. Lord Brahma assured then to find out the reason. He went to the seashore. The sea put the child in his lap and enquired about the name of that child and also about his future.
Meanwhile the child pressed lord Brahma’s neck with such power that tears rolled down from his eyes. For this reason he named the child as Jalandhar. Lord Brahma told the sea that the child will become the mighty ruler of the demons. No deity would be able to kill him except Shiva.
The sea was very pleased by lord Brahma’s predictions. After Lord Brahma returned to his abode, the sea brought that child to his home and brought up that child with great love and care.
When Jalandhar grew up he married Vrinda, who was the daughter of Kalnemi. Later on he became the ruler of the demons.
