Acharya Prashant explains that when individuals speak of God, Brahman, or Allah, the common element remains the 'I' or the ego. While one may profess the oneness of God, they often secretly worship the small god of the self, making them polytheists who prioritize their own ego over the divine. The ego is stubborn and remains unaltered even when religious terminology changes. In practice, people often use the concept of God to placate their own ego, making God dispensable while the ego remains indispensable. The speaker asserts that most people do not truly believe in two gods, but rather only in one false god: the ego.
