Compose an orchestral symphony that captures the journey to one's true self, intertwining elements of the cosmos with the profound discovery of inner identity. Incorporate a blend of ethereal synthesizers to evoke the vastness of the universe, and a delicate piano to symbolize the gentle unfolding of the self. Layer in a dynamic range of strings to convey deep love and passion, building up to powerful crescendos that reflect the emotional and inspiring transformation into the true self. Integrate a subtle choir to add a sense of the epic and the heroic, embodying the true self's capability to bring positive change to the world. The composition should be rich with emotion, ranging from introspective to triumphant, with a tempo around 125 BPM to drive forward momentum. Aim for a sound that is both raw and polished, sentimental yet uplifting, and ultimately, an epic auditory experience that mirrors the poem's themes of self-realization and universal connection
