In fact, he used to make thousands of lingams of Lord Shiva and meditated in front of him all day long. The lingams where casted beautifully out of sand and he took pains to ensure that each lingam was perfect in its shape and structure. Further, he also used to mow the cows and take out the milk which then he offered to Lord Shiva. This was his usual activity. This usually bothered his parents since they were pissed with his activity of playing with sand and milk all day long. One day when Chandikeshwara went for his usual chore of milking the cow, his father entered the spot where he had made his lingams and started shouting at him. In order to find his son, he by mistakenly ruined one of the lingams by stepping onto it. This had been casted and kept by Chandikeshwara. This made Chandikeshwara angry and sad and out of anger he cut off the limb of his father. Pleased with such devotion and dedication, Lord Shiva gave darshan to Chandikeshwara and gave him a boon that his statue would always lie beside his own idol. He further, gave back his father's limb. Since, then Chandikeshwara has been found in all Shiva temples in a meditating posture, In fact, in order to distract his meditation and seek his blessings, devotees make different kinds of sounds with their fingers before entering the temple.
