Dear Gloria
in the following extract:
"Ego is an opiate, and it lets you down every time. Ego is very small. It blinds you and deafens you. It sets traps for you all the time. It is a mine field.
Strengthen your heart, and ego is automatically weakened. Down with ego. Up with heart.
Ego is skinny-livered. Heart is like a thrush’s throat and beats fulsomely. Hurray for heart. Boo for ego.
"
what is the meaning of "thrush's throat" in the context of the heart? A thrush's throat is an infection...
And, is a skinny-liver the opposite of a fast or high liver?
Thanks
