Then said Silaka Sâlâvatya to Kaikitâyana Dâlbhya: 'O Dâlbhya, thy Sâman is not firmly established. And if any one were to say, Your head shall fall off (if you be wrong), surely your head would now fall.'

In plain words: Silaka told Dalbhya that his answer had no firm ground. He warned that if someone had bet his head on it, Dalbhya would have lost it.
