Lord Shiva appeared before Lord Vishnu to provide the boon he needed. But at the same time, Lord Vishnu overlooked Goddess Parvati, the wife of Lord Shiva.
Reacting to Lord Vish Vishnu’s signs of disrespect, she had cursed Lord Vishnu that his son would get burnt away by her Lord. Upset by her words, Lord Vishnu then started worshipping the Lord Shiva, Goddess Parvati and their Child Lord Skanda. Delighted by his worship towards them, Lord Shiva and Goddess Parvati blessed Lord Vishnu’s son to get back to life by the grace of God.
