Aswamedha yagam is the ultimate puja to get the utmost blessings of God. There is a story about this yagam in Maha Bharatha: once an Emperor made elaborate arrangements for performing this yagam. After completing all the formalities, when the priests were about to start the yagam, a mongoose appeared in the yaga mandapam. Its body, except for all the tail, was shining like gold. It had the capacity to speak clearly.
