Today we celebrate Tai Pusam, a festival for fasting and performing public penance, by which we seek Karttikeya's blessings to dispel our selfishness, pride and vanity.
From Dancing with Siva:
What Is the Nature of Lord Karttikeya?
Lord Karttikeya, Murugan, first guru and Pleiadean master of kundalini yoga, was born of God Siva's mind. His dynamic power awakens spiritual cognition to propel souls onward in their evolution to Siva's feet. Lord Karttikeya flies through the mind's vast substance from planet to planet. He could well be called the Emancipator, ever available to the call of those in distress. Lord Karttikeya, God of will, direct cognition and the purest, child-like divine love, propels us onward on the righteous way through religion, His Father's law. Majestically seated on the manipura chakra, this scarlet-hued God blesses mankind and strengthens our will when we lift to the inner sky through sadhana and yoga. The yoga pada begins with the worship of Him. The yogi, locked in meditation, venerates Karttikeya, Skanda, as his mind becomes as calm as Saravana, the lake of Divine Essence. The kundalini force within everyone is held and controlled by this powerful God, first among renunciates, dear to all sannyasins. Revered as Murugan in the South, He is commander in chief of the great devonic army, a fine, dynamic soldier of the within, a fearless defender of righteousness. He is Divinity emulated in form. The Vedas say, "To such a one who has his stains wiped away, the venerable Sanatkumara shows the further shore of darkness. Him they call Skanda."
Lord Karttikeya was not born of God Siva’s mind, he was born of God Siva’s knowledge. because mind is limited boundary one but knowledge is limitless boundary, Lord Karttikeya is limitless knowledgeable god so Lord Karttikeya was born of God Siva’s knowledge.
Proof of mind is limited boundary one, see thirumandiram
சத்தமும் சத்த மனனும் தகுமனம்
உய்த்த உணர்வு உணர்த்தும் அகந்தையும்
சித்தம் என்று இம் மூன்றும் சிந்திக்கும் செய்கையும்
சத்தம் கடந்தவர் பெற்ற சன்மார்க்கமே. – திருமந்திரம்
மனம் – பரந்த தன்மையுள்ள, மனமும்
புத்தி – மனம் பற்றி ஐயுற்ற பொருளை உறுதிசெய்வதாகிய இறுப்பு என்னும் புத்தியும்
அகங்காரம் – அப்புத்தியினை எழுப்புவதாகிய அகங்காரமும்
சித்தம் – தூக்கி எண்ணுவதாகிய சித்தமும்
Don't let down. Success comes with consistency of conduct. Improve and control our mind and behavior standards twenty-four hours a day. Monistic Theism, our tradition, is a dual approach. Worshiping God on the outside; claiming and realizing God on the inside. Going deep within to find That which does not change. The path of Saivism: "Bhakti-raja-siddha yoga leading to oneness."
