विष्णुपुराण - तृष्णा

या दुस्त्यजा दुर्मतिभिर्या न जीर्यति जीर्यतः |
तां तृष्णां संत्यजेत् प्राज्ञः सुखेनैवाभिपूर्यते ||

-विष्णुपुराण

Wicked people can not get rid of it. It does not get weaker in spite of you getting weaker due to old age. Such is the nature of greed. A wise man will realize that he has to distance himself from it. That is the only way he will be surrounded by happiness.
