Greed is the appetite that grows with feeding. A larger salary only raises the number we think we need, a bigger house reveals what it lacks, and winning once makes us hungry for the next win. Greed is not always about money. It can be a hunger for attention, praise, power or experiences, and it quietly erodes fairness, loyalty and peace.
The Gita explains greed through the gunas (qualities of nature). Gita 14.17 says sattva produces knowledge, rajas produces greed, and tamas produces carelessness and delusion. Gita 14.12 lists greed, restlessness and an urge to start new ventures as signs that rajas dominates. Gita 18.27 describes a doer swayed by craving for results, greed and impurity of motive, who is lifted by joy at gain and shaken by sorrow at loss.
The Gita points to the mind's patterns. Gita 16.13 shows a mindset fixed on what it has gained and what it hopes to gain next, never satisfied. Gita 1.38 warns that minds clouded by greed see no fault in harming relationships and society, and Gita 1.45 notes how craving for power and pleasure can lead to great harm. Practise gratitude, pause to examine your motives, and treat your own thoughts as a signal: clarity points to sattva, grasping to rajas.
