A discriminating mind gives rise to feelings.
Those feelings are interpreted and lead to craving or aversion.
Craving and aversion both affect our choices.
Choices create karma.
That is why renunciation is important.
That is why we need to appreciate impermanence.
That is why we need to eliminate perceptual bias.
Meditation is the vehicle that allows us to let go, to see clearly, to see truly, so that we can eliminate the discriminating mind.
