Greed is a form of pollution and is a transgression of spiritual and moral law and is termed evil.
Disappointment is certain if some act is done merely out of greed. Excessive greed blinds the mind. Lobha (greed) is one of the three root sins, along with moha (desire) and krodha (anger), which must be conquered to achieve moksha (liberation). Do not be disillusioned by wants.
Ancient Hindu scripture, Bhagavad-Gita says: there are three gates to self-destructive hell—greed, anger, and desire. Abandon these three. A person freed from these three gates of darkness seeks what is best and attains life’s highest goal.
