In plain words
Unity in multiplicity is the root principle of Prakṛti
Unity in diversity is the root principle of Prakṛti. The people of Bhārat grasped this principle. They do not try to change it. All the other religions have set up some fixed doctrines, accepted and followed those alone, and rest content with their own communities. The people of Bhārat have gone on offering worship suited to each one's own feeling. The work all religions do is to help the growth of physical man and make the divinity within him shine forth. The worships of the people of Bhārat are one Satya taking shape in keeping with different forms, different natures and different circumstances. The breadth of mind to proclaim to every quarter of the world that “God is in all religions” has fallen to the people of Bhārat alone. This is their good fortune. Not to be ashamed of our forefathers is one of the rules of life. The more you read of past history and the more you turn your gaze on the past, the more your pride will grow in you. The forefathers of the people of Bhārat reached great heights. May that complete faith rise into your blood too! May it spread through it! May it become inseparable from your life! In the same way, the chief Vidyā is to believe that every nation and every religion has something of its own.
