Dispelling Sorrow Spell

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."
