Does this kind of meditation have grounding or an equivalent in Buddhism?

I've done a kind of meditation recently (or thought exercise), inspired by Buddhist teachings, and was wondering if the meditation has a specific name in Buddhism? The meditation goes as follows: - Start with a couple minutes of breathing meditation. - Then try and notice any attachments or aversions that I feel in the moment. - For an aversion: - Allow the aversion to be there. - Allow the thing/situation/feeling that I'm avoiding to also be there, even if just for the duration of the meditation. - Try and build a sense of kindness towards the thing/situation/feeling that I'm avoiding. - For an attachment: - Allow the attachment to be there. - Allow the thing/situation/feeling that I'm attached to to be there. - Allow the opposite of the thing/situation/feeling that I'm attached to to also be there. - Repeat above until there is nothing left that I feel attachment or aversion towards. And that's it. I've found that this gives an incredible sense of ease and calmness and presence. Does this have any grounding in Buddhist teachings?
