When understanding comes, continue to be aware – don’t lose your awareness. When you’re happy and don’t continue to watch, then defilement can come.
For example, when some understanding arises, the idea of ‘I’ (‘I know, I know!’) or wrong view also arises because of habit.
So, you need to be smarter than the defilement – you need to know how it works.
In daily life, you need to think more about how to practice.
What you’re doing in daily activities, you already know – there is no need to force to think because the mind already knows how to do them.
You need to think more about how to maintain the awareness, how to practice. Only then, awareness can work strongly; otherwise, you think more about what you’re doing and awareness becomes weak and disappears.
