activating a positive experience and installing it in your brain. - Rick Hanson

To do Linking, a person must be able to hold two things in awareness, keep the positive material more prominent, and not get hijacked by the negative. Practicing mindfulness will increase your capacity to do these things. If you get pulled into the negative, drop it and focus only on the positive. Later on, you can allow the negative to come back alongside the positive in awareness. Most experiences of Linking are fairly brief, under half a minute, but you can take longer if you like.

staying with a negative experience past the point that’s useful is like running laps in Hell: You dig the track a little deeper in your brain each time

You are settling into simply being in the present, letting go of the past and not fearing or planning the future. Nothing to fix, no other place to go, no one you have to be. Rest and relax as a whole body breathing.
