I remember how the little insights arose when I was practicing with my teacher in my teens. 

I would be sitting for an hour – I understood nothing except that I had to be mindful every second. I was very diligent and the sitting would end after an hour when somebody knocked the bell.

I would stop being mindful and got up – and then some insight would arise. I’d like ask: why the insight arose then? It happened several times and I finally understood that, first there was diligence and then the mind relaxed. And when I relaxed, the mind came into balance, but because of the diligence and momentum of mindfulness, the insight could arise when the balance came.

It may not happen this way for everybody, but we have to watch out for how insights arise for ourselves. How was the mind working before the insight arose?

I was very clear that when the insight arose, there was no desire for it to arise.
