Vasudaiva Kutumbakam

            वसुधैव कुटुम्बकम्

       vasudhaiva kuṭumbakam

Meaning:

The whole world is one family.

(“vasudha”  = the earth; “iva” = emphasize/is/indeed;  “kutumbakam” = family)

Expanded meaning:
This verse is considered as the  most  “loftiest Vedantic thought of Hindu Dharma and influenced the mankind ever since. It is engraved in the entry to India’s parliament building. This phrase is part of the mantra VI-72 in Maha Upanishad. The mantra reads:

अयं बन्धुरयंनेति गणना लघुचेतसाम्
उदारचरितानां तु वसुधैव कुटुम्बकम् ॥

Meaning – the distinction “This person is mine, and this one is not” is made only by the narrow-minded (i.e. the ignorant who are in duality). For those of noble conduct (i.e. who know the Supreme Truth) the whole world is one family. 

It is a fact that emerged from the observation and analysis by the Scientists of the day and recorded in their reports. The Scientists were the Seers, Rishis. Their reports were the Upanishads. The Upanishads were the foundation stones on which the magnificent sanaatana dharma developed.
