For a still better manner of worship, we perform abishekam with milk, honey sandal paste, panchamirtham etc to the deity. For a still better worship, we make a human or yagam in order to please God. The top most form of worship as per our Vedas is performing Aswamedha yagam.

Aswamedha yagam cannot be performed by ordinary people. It requires a lot of resources and personnel. Not even the Rajas and Maharajas can do it. Only Emperors, like Dasaradha, Asoka etc who have vast territories and a good number of Rajas and Maharajas under their control, could perform this yagam, as it needs hundreds of yaga kundams, very big yaga mandapam, tons of ghee and other materials and hundreds of Brahmin scholars who were well versed in the Vedhas.
