Premanand Maharaj Ji
Where does greed come from in the mind?
Greed grows out of desire
Greed has no separate existence; it is born when a desire gets fulfilled, just as anger is born when a desire is blocked. Desire, anger and greed are the three destroyers, and they corrupt the intellect.
Greed does not exist on its own; it comes from desire. When a desire is fulfilled, greed arises; when a desire is blocked, anger arises.
