A golden poster with a picture of a cross and a mountain

Create a logo for the 'Produtividade Saudável' blog, which is in Portuguese, that embodies the concepts of modernity, technology, health, balance, and self-improvement. Utilize colors and elements that evoke a sophisticated yet harmonious feel, while incorporating symbols or objects that complement the overall message. Additionally, infuse elements that suggest the idea of spiritual transition and the dawn of a new golden age for humanity. The logo should reflect a contemporary, cutting-edge aesthetic. Provide the image in high definition upon completion.
