न चिरं पापकर्माणः क्रूरा लोकजुगुप्सिताः । ऐश्वर्यं प्राप्य तिष्ठन्ति शीर्णमूला इव द्रुमाः ॥७॥

— श्रीमद्वाल्मीकिरामायणे अरण्यकाण्डे एकोनत्रिंशस्सर्गः (६ श्लोकम)

Continuing the advise, ShriRaama spoke to Khara:

“This world has a strong aversion for the cruel-minded. Like how even a giant tree slowly dies off if its root is affected, adharmic people will in no time loose even great fortunes (that they obtained because of some good deeds in the past) owing to their cruel acts”.

In the guise of this shloka ShriRaama is teaching us that Dharma is the root for one’s prosperity.
