In plain words
One cannot avoid admitting that Bharatiyas showed unrestrained boldness in philosophical inquiry. Even a mere spark of their daring flame of conviction is capable of instilling awe among Western philosophers renowned for their own boldness.
On this very matter, Professor Max Müller spoke beautifully. However far reasoned inquiry led these bold thinkers into unfamiliar conceptual territory, they dared to go there. Whatever they had to renounce for it, they did not draw back. What people might think of them troubled them not at all. Whatever seemed proper to them, and whatever seemed true, it was for the sake of that alone that Professor Max Müller exhorted the people of the world to enter the river of Bharatiya paramartha.
'Ekam sat viprāḥ bahudhā vadanti' — 'There is but one entity; the wise call it by different names' — this is what this verse contains, and the truth it holds is of the most sublime kind. In Bharat, the entire spiritual inquiry that has prevailed through endless time rests upon this one root-principle alone. Whatever theistic inquiry is yet to spread anywhere in the world in the future will likewise be able to rest upon this alone. It stands as the very outlook of those who composed hymns about these various deities. There is but one seer who beholds; it is the many who are the cause of apparent difference. Concerning that one and the same, sole Supreme Person, hymn-composers, ṛṣis, and poets composed songs in various languages, with various expressions and various conceptions. From this verse — 'Ekam sat viprāḥ bahudhā vadanti' — a most exalted outcome has arisen. That Bharat alone has been free of religiously-rooted violence and of obstruction to religious observance may seem strange to some. Theists, atheists, non-dualists, dualists,
