The Mahabharata (Markandeya Samasyaparva) describes a story of a baby born from the brilliance of Siva, of which Indra is afraid. The baby named Guha/Skanda, raises a loud cry which makes all the Devas trembled with terrible fear. Indra throws his thunder-bolt on Skanda, which results in the birth of a goat-faced youth from the right side of Skanda and he is known as Vishaka. However, it may be noted that Guha and Vishaka are merged in Skanda. 
Vaikasi Vishakam celebrates the anniversary of Lord Karthikeya’s creation. It was in this month (May-June) that Lord Muruga was born with Vishakam as His birth star.
