Arthashastra
शत्रोः शङ्कित अमात्येषु सान्त्वं प्रयुक्तं शेष प्रयोगं निवर्तयति, दूष्य अमात्येषु दानम्, संघातेषु भेदः, शक्तिमत्सु दण्ड इति ॥
Conciliation used toward an enemy's suspicious ministers prevents the employment of other methods. Gifts are used for corruptible ministers, dissension for those who are united, and punishment for those who are powerful.
