Our thoughts can be divided into 2 categories – Idam Vritti or Aham Vritti. In Aham Vritti, we have and identify with “i” thoughts, producing “I am” as related to our limited egocentric personality. Idam Vritti refers to thoughts of the world outside, which are all also based on thoughts of ourselves. So it can be concluded that “i” is a constant in our thoughts. Our mind can thus be defined as a flow of “i” thoughts that creates our individuality.
