Let it go

Let it go.
Be aware of it.

This is all I've leaned in the meditation workshop.

Feel whatever negative or positive feelings and acknowledge them without judging, and let them go.
I was walking on the way to school, saying "Let it go" in my mind.
The most hard thing is being aware of what I am feeling without judging.
What I'm confused is that if I don't judge any feelings, I can't know even negative or positive minds
If I precisely follow the idea, I may not distinguish even good and bad things.
However, it is almost impossible because usually we judge things in the dualistic way.
Yes or no.
Good or bad.

When I want to let thins go, actually the things must be negative.
The reason is because I don't have to let things go when they works positively.

Acknowledge everything rather than let them go.
