How to see the hidden demons within?

The following is an excerpt from a samvaad (dialogue) session with Acharya Prashant.

Questioner (Q): There are certain things that we can observe very easily. But there are certain things that are not very obvious, that cannot be detected obviously.

I have noticed this very recently that when I get into discussions related to Spirituality, especially with my wife, it becomes more of a competition than discussion, and becomes a matter of ego.

There may be many more such hidden tendencies that I am unable to observe generally. Is there something else that can be done to dig them out?

Acharya Prashant (AP): Everything will show up in your behavior.

Behavior can remain externally defined, and disciplined, and regulated only as long as the conditions in which that behavior is being displayed remain pre-defined and pre-regulated.

If your meditation and spiritual practice have any worth, then your external conditions will change. And when your conditions change, you will no more be able to negotiate the new conditions with old behavioral patterns. So new behavior patterns will emerge. Those new behavior patterns are bound to tell you something about yourself.

Please understand this.
