Under the influence of false ego one thinks himself to be the doer of activities, while in reality all the activities are carried out by nature as natural process

Bhagavad Gita, Chapter 3 verse 27

Here, in the Bhagavad Gita (The Lord’s Song), Krishna tells his friend Arjuna a great truth: that the notion of there being any separate entity that takes itself to be the doer is false. There is no doer, the ego is a false entity; there is only nature acting according to its own inherent principles.
