Before the Kumaras, Lord Brahma first created the five forms of agyaan (ignorance) :
1) andhatamisra – the idea that one would die
2) tamisra – indignation
3) maha–moha – craving of infatuation
4) moha – delusion of errors
5) tamas – absence of knowledge about one’s own engagements
Seeing such a misleading creation as a sinful task, Brahma did not feel much pleasure in his activity, and therefore he purified himself by further meditation. Then he began another term of creation.
This resulted in the creation of the four Kumaras – Sanaka, Sananda, Sanatana and Sanat-kumara.
But when these four refused to generate progeny, anger (krodh) was generated in the mind of Brahma.
Although he tried to curb his anger, out of his anger from between his eyebrows instantly a child who was red (for passion) and blue (for ignorance) was born.
The child cried loudly to his ‘father’ and requested him to designate him a name and a place.
“As you were crying out aloud the moment you were born, people will address you with the name Rudra”, Brahma pacified the child by first giving him a name.
“The heart, the senses, the air of life, the sky, the air, the fire, the water, the earth, the sun, the moon and austerity are places for your residence”.
“Manyu, Manu, Mahinasa, Mahan, Siva, Ṛtadhvaja, Ugrareta, Bhava, Kala, Vamadeva and Dhrtavrata are your 11 other names”
“Dhi, Dhrti, Rasala, Uma, Niyut, Sarpi, Ila, Ambika, Iravati, Svadha and Diksa are your eleven wives (the Rudranis).”
“You are the master of the living beings. Accept these different names and places and the wives belonging to them and increase the population on a large scale” Brahma asked Rudra.
Rudra generated unlimited sons and grandsons. All of them assembled together and attempted to devour the entire universe. When Brahma saw this he became afraid of the situation and requested Rudra to stop generating living entities of this destructive nature.
He advised his son Rudra to undergo penance which would result in creation of the universe as it was before.
Rudra took leave from his father and started performing austere penances.
Thus the second attempt also didn’t yield desired dividends for Brahma.
