सुभाषितसुधानिधि - मंत्रविस्रवः

एकं विषरसो हन्ति शस्त्रेणैकश्च बाध्यते ।
सराष्ट्रं सप्रजं हन्ति राजानं मन्त्रविस्रवः ॥

- सुभाषितसुधानिधि

Poison could kill one person. You could kill only one person using a weapon. But using a weapon of thought, one can destroy not just the king, but an entire kingdom including the state and its subjects.
