Arthashastra
यथा सामन्तानाम् आमिष भूतः सामन्त व्यसनजो लाभः, शत्रु प्रार्थितो वा स्व भाव अधिगम्यो लाभः, पश्चात् कोपेन पार्ष्णि ग्राहेण वा विगृहीतः पुरस्ताल् लाभः, मित्र उच्छेदेन संधि व्यतिक्रमेण वा मण्डल विरुद्धो लाभः इत्य् आपद् अर्थः ॥
for example, wealth which is enjoyed in common by neighbouring kings and which is acquired at their expense; or wealth which is asked for by an enemy; or wealth which is seized like one's own property; or wealth which is acquired in the front and which causes future troubles or provokes an enemy in the rear; or wealth which is obtained by destroying a friend or by breaking a treaty and which is therefore detested by the Circle of States--all these are the varieties of dangerous wealth.
