...is the remedy for people who have reached the limits of endurance. They have explored all avenues and see no way out of their difficulties. They feel there is nothing left for them but annihilation and emptiness.
Whereas people in a Gorse state decide to give up when there are possible solutions untried, the person in a Sweet Chestnut state is genuinely at the end of the line: theirs is appalling, final despair.
In this extreme state, the remedy helps us remain masters of our lives, and renews our hope and strength. Sometimes a way ahead may open even when we expect it least.
Dr Bach's description
For those moments which happen to some people when the anguish is so great as to seem to be unbearable. When the mind or body feels as if it had borne to the uttermost limit of its endurance, and that now it must give way. When it seems there is nothing but destruction and annihilation left to face.
