All the usual that anyone would. Hugs. Words of comfort. Love. Kindness. I know that.
Do we have other, additional, aspects that we can add as Buddhists ? A perspective on eternity ? Our never dying non-selves, joining the cosmos ? That something can never become nothing, on a pure physical level ? All to be provided at the right time, obviously. Sensitive times, calling for serious compassion.
This is really needed here, hoping for some words of help.
