Does anatta cause dynamic emotions? I read the following on the internet:

In an uncultivated individual the emotions rule the self. This is the
result of lack of understanding of Anatta and somehow the individual
is putting conscious effort into the stagnation of their naturally
dynamic emotions.
Emotions are naturally dynamic and a result of environmental
influence, which is also dynamic - so in that sense Anatta is
applicable.

What are &quot;dynamic emotions&quot; in Buddhism?
Does anatta or its realisation stop the stagnation of naturally dynamic emotions?

&quot;Dynamic emotions&quot; is somewhat sloppy language. It just means that samsaric phenomena, in this case emotions, are in a constant flux. They are ever-changing and arise and cease incessantly and without any control.

Sorry, I didn't understand this question. You write &quot;stop the stagnation&quot; - do you mean if the natural process of exhaustion of causes and conditions can be stopped by realizing Anatta?
There are 3 gateways/doors to liberation - truly realizing and understanding Anatta is one of them. So in that sense, the process of becoming can be stopped by winning Nibbana, thereby issuing liberation from the rounds of suffering.
