Kalbhairav is a manifestation of Lord Shiva and a total imitation of Shiva. When Lord Brahma and Lord Vishnu squabble about their enormity.
The starting point of Bhairava can be followed to the discussion among Brahma and Vishnu described in the Shiv Mahapuran where Vishnu asked Brahma who is the incomparable maker of the Universe.
Pompously, Brahma advised Vishnu to revere him, he being the preeminent maker. One day Brahma thought, "I have five heads, Shiva likewise has five heads. I can do all that Shiva does and along these lines I am Shiva" Brahma had gotten somewhat self absorbed.
Not just had he got selfish, he began to manufacture crafted by SHIVA. BRAHMA began meddling in what Shiva should do.
At that point an enormous Agnilinga showed up beween them. Both the divine beings attempted to see the closures of linga top and base separately. However, they neglected to arrive at the finish of Shiva linga.
In any case, Lord Brahma lied that he saw the end and Lord Vishnu acknowledged his disappointment genuinely. On that event Lord Shiva came and cautioned Brahma to quit lying. However, Brahma offended Lord Shiva.
At that point Mahadeva (Shiva) tossed a little nail from His finger, which accepted the type of Kala Bhairava, and calmly went to trim the head of Brahma.
Kal Bhairav trim the fifth head of Brahma. At that point Brahma perceived his slip-up, and lauded and requested that Shiva excuse him. At that point Kal Bhairav left Brahma.
Master Brahma and Lord Vishnu recovered their insight and left their pride and personality. At that point Lord Shiva told that "Ones information won't be celebrated until he has pride and sense of self.
One who eliminates his pride and conscience will know the God. God will annihilate people with incredibly pleased. The god who eliminates pride was conceived."
This implies Kal Bhairav will eliminate Pride and Ego, he won't endure lying, he adores truth.
As the Kaala Bhairava, Lord Shiva is supposed to monitor every one of these Shaktipeeths. Each Shaktipeeth sanctuary is joined by a sanctuary devoted to Bhairava.
