Suresha Paddhati is a form of Vedic Jugalbandhi. It is a method of reciting Samhita and other Vikrutis, like Ghana Patha from more than one Veda.
In this case Rig Veda and Krishna Yajur Veda are recited immediately and simultaneously, to highlight the difference in svara, pada, the place of its occurrences and the sandhi and grammar rules of the respective Vedas. It also seems that there is a verbal competition between the Vedas that are recited.
We demonstrated this on stage by inviting Vedic Pandits and reciting the well known Sandhya Vandana Mantras and the Ghana Patha version of the mantras.
The avid listener can observe the differences and appreciate the nuances in recitation of both the Vedas.
