How to cultivate the perception of 'Anatta'?
Well, it's actually not that difficult. Stop thinking in terms of persons and start thinking in terms of information, tendencies, and influences.
When you see a person doing something, don't think: &quot;this person has decided to do this and that&quot;. Instead, think in terms of influences: there were these circumstances that formed this view and led to this behavior.
Similarly, when you think about yourself, don't think &quot;I have decided to do this and that&quot;. Think, &quot;here are the habits, here are the influences, here are the attachments, here are the stereotypes, here are the reactions, here is the knowledge of Dharma - and here's the behavior emerging from the interaction of all of the above.&quot;
For those who prefer official Theravada terminology, think in terms of skandhas. The key thing to understand is, they are not found inside a person. They span people and time.
And of course, the most essential Anatta practice of all: never acting to benefit one's ego.
