This man, the first born of the God, was tied to a wooden sacrificial post and the gods and the Kings along the seers performed the sacrifice

"Thamevam Vidwanamruthaiha bhavathyNanya pandha ayanaya vidyathe"
This (sacrifice) is the only way for redemption and liberation of mankind. Those meditate and attain this man, believe in heart and chant with the lips, get liberated in this world itself and there is no other way for salvation too
