The essential practices that give rise to liberation are mindfulness, concentration and insight.
Leaking – asrava
While you are doing something you imagine that later in the day you will rest in your bed and read that very interesting book you started.
When you become aware of the fact that with your mind you are in the future, having an unfulfilled wish that you want to fulfill, that is a leak – nothing to get upset above – just notice and return to the present moment, with all of its wonders.
