Lord woteth there that soul is that, for abundance of brenning
love, is worthy to hear angel's song. Who so then will hear angel's
song, and not be deceived by feigning of himself, nor by
imagination, nor by the illusion of the enemy, him behoveth for to
have perfect charity; and that is when all vain love and dread, vain
joy and sorrow, is cast out of the heart, so that it love nothing
but God, nor dread nothing but God, nor joyeth, nor sorroweth
nothing but in God, or for God. Who so might by the grace of God go
this way, he should not err. Nevertheless, some men are deceived by
their own imagination, or by the illusion of the enemy in this
manner.[169] Some man, when he hath long travailed bodily and
ghostily in destroying of sins and getting of virtues, and
peradventure hath gotten by grace a somedeal[170] rest, and a
clarity in conscience, anon he leaveth prayers, readings of holy
scriptures, and meditations of the passion of Christ, and the mind

by working of the wicked enemy that feigneth such sounds in his
hearing.

For if a man have any presumption in his fantasies and in his
workings, and thereby falleth in to indiscreet imagination, as it
were in a frenzy, and is not ordered nor ruled of grace, nor
comforted by ghostly strength, the devil entereth in, and by his
false illuminations, and by his false sounds, and by his false
sweetnesses, he deceiveth a man's soul.

And of this false ground springeth errors, and heresies, false
prophecies, presumptions, and false reasonings, blasphemings, and
slanderings, and many other mischiefs. And, therefore, if thou see
any man ghostly occupied fall in any of these sins and these
deceits, or in frenzies, wete thou well that he never heard nor felt
angel's song nor heavenly sound. For, soothly, he that hea
