Any identity is called Ahamkara (ego). Aham + Aakara = Ahamkara. Aham means I/me/my. Ahamkara means binding ourselves to some Aakara (identity). Aakara means shape, which is always limited. Similarly, any identity of ourselves is limited. We make various type of identity and name it for example male/female, edult/child etc, by religion, by age, by cast, by amount of money, and hundreds of name (or label) of our type. That is called ego.

Identity shapes our actions and emotions. Ego have major rolls to decide likes and dislikes, and also priorities the things. For example, I am Indian. “Indian” is my identity, which separates me from people of other countries.
Another example is “This is my family.” By saying this, I feel more responsible toward my family first before others. Ego can lead is to miserable situation.

There are 2 ways for not being miserable becouse of ego. First way is everything belong to me. It means i like everything and everyone. There is no other side.
the Second way is the nothing is mine. So i dont need to worry about anything. There is no question of like and dislikes.

A Contradiction of “I am”

In Indian scriptures, it is said:
“अहं ब्रह्मास्मि” – I am Brahman.
This means I am the ultimate reality of this universe. I am the same consciousness as the universe itself, the same force as God.

The second aspect of ego is: I am nothing in this infinite universe. I am like an atom, insignificant. The universe is self-driven. There is nothing important about me. There is nothing to worry about!

Both aspects—“I am everything” and “I am nothing”—are universal truths. We just need to be aware of them.
