The "Nastaleeq" Script is one of the most beautiful form of Arabic Calligraphy.
As it is apparent from the image above, the cursive nature of "Nastaleeq", and the balance between thick and thin strokes create a marvelous visual experience for the viewer.
The bottom to top flow of writing is one of the widely used in "Nastaleeq".
Salaam.
