Sadhguru
Why do I feel greedy, and how do I stop?
Greed is a search for fulfilment
The answer is the same for greed, anger and hatred: we are unable to bear the incompleteness of who we are, so we try to find fulfilment through a person or through what that person has. If you realise it is not getting you anywhere, be sensible enough to shift.
Somehow you want to fulfil yourself, because you cannot bear the incompleteness of who you are. Try hard, and it will not get you anywhere.
