Vishnu decided to assume the form of Mohini...so as to procreate with Shiva... Shiva is overcome with passion on seeing "her" form and unites with her. Lord Ayyappan is born from this union of Hari and Hara... Ayyappan combines the strength of both Vishnu and Shiva and hence, is invincible... Parvati...collected all the sandalwood paste on her body and made a figure of a little boy out of it. She then gave it life and asked this son of hers to guard the gate when she went to bathe... Shiva beheaded him when Ganesha came between Shiva and Parvati. Shiva then replaced Ganesha's original head with that of an elephant... Ganesha...is one of the most popular deities in the Hindu pantheon... Murugan...is another son of Shiva and an equally popular Hindu deity... Lord Kartikeya is portrayed as a very beautiful deity, with six heads and twelve arms...
