IMS Retreat 2012 Q&A Group B#1 (11:15-12:48)
Yogi: Gaining insight into thinking – that it is an object, nature or simply the mind – is it an investigation through experience and questioning?
Sayadaw: The insight is a realization through observation.
You just have to observe a lot to gain more experience until the mind is ready to understand it.
Knowing if something is skilful or not, or if it is right or wrong, just understanding this is a level of wisdom or insight.
