Hi Edu,
I echo Cloud. Your English is just fine.

When you do PA meditation, you feel the No-thing-ness. Then you have Eufeeling coming to you.
It may take a little while, trailing no-thing-ness.
Then while you are staying in Eufeeling, look at a surroundings. But not the things, objects, but the space between you and the object you are looking at. That space is PA. You can feel the PA without being aware of the contents of awareness.
The main thing is have fun doing it. Enjoy!
