Yogi: I feel cheated – I’ve attended 70 retreats in the last 40 years and don’t seem to be any closer to nibbana.

Sayadaw: It is only a mind that is free of defilements, a pure mind that can take a pure object – only a pure mind is able to realize nibbana.

The principle is that the mind receives the experience that matches its quality. The only thing we can do is to purify this mind as much as we possibly can because that’s how much closer it gets to experiencing what is more pure.

Experiential wisdom must arise for real purification to happen because it is wisdom that purifies the mind.

The problem with all of us is that we’re not able to sustain the process of purification in our lives. That’s all.
