National Motto - Satyameva Jayate

Interestingly many countries like Japan, China, Russia don't have National Motto.
National motto is essentially printed on currency notes.

• Just like our Indian Rupee notes have  सत्यमेव जयते  below the national symbol (4 lions)
• Similarly US dollars we can see "In God we Trust" a very interesting one to me being so advanced in technology. 
• Nepal too has interesting (familiar phrase to Indians) - जननी जन्मभूमिष्च स्वर्गादपि गरियसि (Janani Janmabhoomischa Swargadapi Gariyasi)

The comprehensive list of national mottos is here on Wikipedia
