As Mantras applied for gaining victory, or the performance of the Soma sacrifice made without proper gifts, or oblations poured on the fire without proper hymns, become fruitless and produce evil results, so sin and evil results originate from falsehood.
यन्मन्त्रे भवति वृथोपयुज्यमाने यत् सोमे भवति वृथाभिषूयमाणे। यच्चाग्नौ भवति वृथाभिहूयमाने तत् सर्वं भवति वृथाभिधीयमाने॥
