Can mindfulness help my family member heal emotional pain per his chart?

A family member of mine has been feeling down lately. They've gone through a lot — ups and downs that have seemed to have left a permanent mark on their heart. At times, they attempt to be strong for everyone else, but I could sense there's still so much pain that they bear silently within. I've actually begun to wonder if astrology could help here in some way. Maybe his birth chart shows what kind of mindfulness exercises could actually help them heal. I am curious if mindfulness might help them let go and feel better both emotionally and bodily, to help them to reconnect with that inner calm they have not felt in ages.
