"Rue" Afza to Rooh Afza

Rooh Afzaa is a drink : here its is description from Wikipedia:
Rooh Afza is a a popular concentrated syrup invented by Hakeem Abdul Majeed and manufactured by the companies he founded, Hamdard (Wakf) Laboratories, India and Hamdard (Wakf) Laboratories, Pakistan, since 1907. The inventor never explained his choice of the name Rooh Afza, english speakers often refer to it as 'rose syrup'. It is a natural cold drink and a blend of pure crystalline sugar, distilled extracts of citrus flowers, aquas of fruits, vegetables and cooling herbal ingredients processed to impart its taste. Hakeem Abdul Majeed claimed that Rooh Afza was concocted using Unani medical principles. However, it is said that Rooh Afza means "that which tempts your soul" because "rooh" means soul and "afza" means which tempts.

Pay special attention to the last sentence. Sad folks are tempted to be "rue"ful and that takes the fun away from their soul - so trigger the ROO, banish the "rue" and enjoy the elixer of life.....just like every sip of the Rooh Afzaa.
