Their deepest and their highest I will sound,
Want when they want, be filled when they abound,
My proper self unto their self extend,
And with them too be wrecked, and ruined in the end.
Mephistopheles.
Believe thou me, who speak from test severe,
Chewing the same hard food from year to year,
There lives (were but the naked truth confessed)
No man who, from his cradle to his bier,
The same sour leaven can digest!
