Vasudhaiva Kutumbakam - वसुधैव कुटुम्बकम्

Vasudhaiva Kutumbakam 
 Indian philosophy that inculcates an understanding 

that the whole world is one family. 

The concept originates in the Vedic scripture Maha Upanishad (Chapter 6, Verse 72):

अयं बन्धुरयं नेति गणना लघुचेतसां उदारचरितानां तु वसुधैव कुटुम्बकं 

ayam bandhurayam neti ganana laghuchetasam udaracharitanam tu vasudhaiva kutumbakam

Only small men discriminate saying: One is a relative; the other is a stranger. For those who live magnanimously the entire world constitutes but a family.
