The legend - Shilad Rishi was following the Bramhachari Vrat, which in his mind feared that his offspring would not move forward. Because of his fear, he wanted to adopt a child, but he wanted to adopt a child who received the blessings of Lord Shiva. That is why he started worshipping Lord Shiva. Lord Shiva was pleased with the penance of Shilad Rishi and gave a vision to Shilad Rishi and asked him to ask for a blessing. Then Shilad Rishi told him the wish of his son in a blessing. Lord Shiva gave him the gift of attaining a son and became introspective. After some time, Shilad Rishi found an infant in the field with a very sharp face on his face. As soon as the sage raised the baby, it was predicted that this is your only son and you should nurture it.
The same child was named Nandi by the sage. Shortly after bringing the child along, Shilad Rishi came to know that his child was short-lived and as soon as Nandi came, he started laughing and told his father that you had received me with the blessing of Lord Shiva and also protected my life. Lord Shiva will do it. With this, Nandi went to do the penance of Lord Shiva and was pleased with the penance of Nandi and appeared before Lord Shankar Nandi and asked Nandi to ask for the bride. Seeing Lord Shiva before him, Nandi forgot about his short-lived age and expressed his desire to live with Lord Shiva in a blessing from Lord Shiva, so that he was happy that Shiva gave him the face of a bull and his vehicle. Friends, devotees and their Ganas provided first place.
