Vinayaka Utpatti (Birth of Ganapathi) is one of the four main stories of Ganesh Chaturthi Puja. Vinayaka Chavithi Vratha Katha is recited after the completion of Ganapathi Pooja.
The story goes like……
In Kailash, Parvathi heard the arrival of her husband and felt very happy. She thought of completing her bath to welcome him. While doing so, un-mindedly she prepared a small toy in the shape of a boy. She had given life to that toy with the help of “mantra” which she learnt from her father. She put that handsome boy for watching and went in side. Mean while, lord Siva came. He was halted by the boy, and not allowed to go in.
Lord Siva came in a rage, towards the restriction for him in his house itself. He cut off the boy’s head and went inside. Parvathi came to know the event that took place and felt sad of it. Siva also felt sorry for the untoward incident and immediately he joined the head of ‘Gajaanana’ that was available with him. He also attributed the foreverness and respectability from all over the universe. Ganesh became the loved one of Siva and Parvathi. Afterwards kumara swamy was born to Siva and Parvathi.
