Yogi: Is everything that appears in the mind impermanent? And is the knowing itself impermanent?

Sayadaw: It’s clear that it is impermanent – that is why we keep losing our mindfulness. We cannot be continuously mindful all the time, right? 

When the mindfulness gains momentum, and when it starts to feel like the mindfulness is doing its own work, it can really feel like the flow of mindfulness is not impermanent, but that it is always there. 

We don’t try to be mindful, but we keep knowing things. When the mindfulness is that continuous, bring the attention to the mindfulness itself. 

We can see that although mindfulness continues on its own because of the momentum, it is also arising afresh every moment.
