To Only Hear the Truth

is to refer to the last parentheses.

Spell
Separate the truth from false and lies

Enchant (his/her/my) ears, enchant eyes

May it be far or may it be near

The truth be revealed to both eye and ear

Effect(s)
If someone were to lie to you then you would hear the truth instead of the lie. Someone would lie to you and say they had gone to the library but because it was a lie, you would hear I had gone to the game arcade. The same goes to what you see.
