Why is truthfulness so important?
No dharma equals truth
The Ramcharitmanas says there is no dharma equal to truth, and the Agam, Nigam and Puranas say the same. God's very name is truth.
No dharma is equal to truth. The name of Bhagwan is itself truth, and in the Shrimad Bhagwat Bhagwan Shri Krishna is praised by calling Him truth.
