Being able to accept suffering and unpleasant states, and be interested in them, that is a kind of understanding. When we have that understanding, it allows us to be okay; it means that we are being mindful.
In those moments when the mind has wrong attitude, when the wrong attitude is there, then it’s very difficult. Always remember that when the mind is upset, when it is feeling dissatisfied or depressed, that’s when the mind has the wrong attitude.
And when the mind has the right attitude, all the wisdom that you have, they all come up again.
You need to understand only one thing – an object is just an object – that alone is enough if you understand it deeply.
