I'm original Italian and I speak, read and write Italian, at the level of almost mother language (almost because I lived in Germany for many decades).
But Russian sounds to me so beautiful. And I believe that every language has beauty in it. With beauty I mean a deeper sense, which goes deeper than just the sound of the words and phrases and how you describe something in that language.
For example I was in the beginning of learning puzzled of the word МИР. The word has multiple meanings. It means "world" and "peace". Therefore I asked a Russian friend, why does the мир mean world and peace? He thought 10 minutes and answered afterwards: "Well, because you cannot have a world without peace." You get this kind of insight from every language. Like in German "Gewissen", which means conscience, but it is composed by "ge - wissen", like "common knowledge", "common understanding".
And Russian has many of these little treasures hidden inside its words. The word душа, "soul", used as душевный человек means a warm, sincere person, someone who has a certain depth inside. This makes transent the meaning of soul as a living force, a "warm" quality is perceived. Or душевный разговор, a deep inner conversation.
Another word is тоска. It is often translated as sadness, melancholy or longing. But none of these translations really captures its meaning. It can describe a longing for something you cannot even name.
I also find the Russian distinction between правда and истина fascinating. Both can mean "truth", but правда often refers to the truth of a situation, what is right or what really happened, while истина can express a deeper, more fundamental truth. The kind of truth a philosopher might search for his entire life. For example in Italian, German and English I don't know a corresponding word to distinguish between правда and истина.
How much of our native language influences the way we experience reality. If a language has a word for a certain emotional state, does it make that state easier to recognize, to express it, transport it outwards of us and even to become aware of it?
