Hello itsgettinglate: I practice this. Where I use it is mostly with regard to difficult memories. When they come up, I focus on them momentarily, I allow them to be present in my mind. I imagine myself breathing into them. I may also smile to them & sometimes even place my hand over my heart as a sign of compassion & lovingkindness toward them. Then I simply allow them to drift away at their own pace. They are like ugly, but powerless, little trolls. They can have no control over me other than what I give them. So I work to accept them... with compassion...
