He is the god of intelligence too. For the following reason: he and his brother subrahmanya being of an age to know woman, their father and their mother told them that they would marry the one that went round the world he swifter. At these words subrahmanya set off at once like an arrow. Instead of dashing after him and trying to oustrip him, Ganesa first of all saluted his parents most respectfully,then began to go seven times from left to right, around them “Why do you do this ?” they asked him. “Is it not written in the Vedas that the son who does seven pradakshinas about his parent has as much merit as he who goes seven times about the world”
This aptness of wit and respectful filial submissiveness brought Ganesa not one wife, but two, buddhi and siddhi , wisdom and success.
Karttikeya, God of war. The circumstances accompanying the creation of subrahmanya –called also SKanda or Karttika ---are at least as strange as those that surround the making of this brother Ganesa .
The rishis, being molested by a gigantic Asura,brgged Siva to give them a defender . Then, opening his third eye, he plunged its glance into Lake saravana. At once there rose from the bottom of the waters six infants. The wives of the six rishis suckled them.
Paravati wanted to embrace the six babes all at once, but hugged them so that they were henceforth one single child, whose body was topped with six heads . And this miraculous infant was to cleave in twain the formidable Asura, the terror of rishis . Of the two parts of the giant one became a peacock ---the hero took this for his mount---the other a cock, the image of which he put on his standard . Karttikeya is a warrior-god. He commands are Siva’s troops. He has four arms, but occasionally only one head.
