This one is from Valerie Worth in her book "The Crones Book Of Words."
When world and fate
Conspire to mark Your life with lines
And characters dark,
Mould a tablet
Of earth or clay,
Write on it all
You would cast away-
All you regret,
All that you bear,
All that afflicts you,
All that you fear-
Break it and bury it
In the ground,
saying this charm
To heal the wound:
"Sorrow be dust
And dust dissolve:
Let my grief
Go into this grave."
