According to the Bhagwad Gita, with the mode of your passion (i.e. your desires and wishes), greed develops; and when greed develops in you, you will become a greedy person. And you will become a selfish and unkind. You will fervently to commit anything in order to accumulate more money and wealth, no matter whatsoever happens. You will only dream to gather more wealth and material things. Your mere desires and wishes will turn into your burning desires and wishes to achieve everything, whether fair means or unfair means. You will want to fulfill your desires and wishes at any cost. Then, you will dig the well of your own downfall and doom. That is why it refers that your greed will lead you to the door of hell.
