Al-Latifah

AL-LATIFAH لطيفة
A term used by Sufi mystics for any sign or influence in the soul, derived from God, which has such a mysterious effect on the heart that mortal man cannot express it in language, just as a delicious taste in the month cannot be exactly expressed by the tongue. (Kitibu ‘t-Ta’rifat, its locc.)
