"He who is the disciple of Khidr [an invisible master] possesses sufficient inner strength to seek freely the teaching of all masters. Of this the biography of Ibn 'Arabi, who frequented all the masters of his day and welcomed their teachings, offers living proof." Ibn al-'Arabi translation and adaptation: Henry Corbin
Lady Macbeth:
Why did you bring these daggers from the place?
They must lie there. Go carry them, and smear
The sleepy grooms with blood.
Macbeth:
I'll go no more.
I am afraid to think what I have done;
Look on't again I dare not.
Lady Macbeth:
Infirm of purpose!
Give me the daggers. The sleeping and the dead
Are but as pictures; 'tis the eye of childhood
That fears a painted devil.
Macbeth Act 2, scene 2, 45–52
