Almost every line here follows the same pattern: silence brings one thing, and then, right after, its opposite. Happiness meets sadness, calm meets rage, wisdom meets arrogance, strength meets weakness. The repetition of "Silence brings" gives the poem a steady, chant-like rhythm, while the swinging pairs keep the reader slightly off balance.
The speaker doesn't seem to pick a side. Instead, the poem suggests that silence has no fixed character. It can soothe or torment, sharpen your thinking or scramble it, depending on who is experiencing it and in what state of mind. The second-to-last line, "Silence brings what silence brings," almost shrugs, as if the speaker has run out of ways to describe something so slippery.
The final line, "Silence brings conditions," lands as a quiet answer. Silence isn't good or bad in itself; it depends on circumstances. The mood is reflective and even-handed, a little restless, but ultimately thoughtful and calm.
