Create an abstract background design titled 'Cycle of Life' that captures the essence of continuity and renewal through an artistic lens. The design should showcase a dynamic, repeating pattern of circles in varying sizes, thoughtfully scattered across an expansive negative space. Each circle embodies a cycle, symbolizing the fluidity of life and the natural rhythm of beginnings and endings, enhanced by soft, minimalistic effects like gentle gradients and subtle shadowing to accentuate their ethereal quality. Utilize a pastel color palette, with a predominant soft pastel purple serving as the backdrop. The circles should be rendered in crisp white, with delicate accents of complementary shades such as light lavender or pale pink to create depth and visual intrigue while maintaining a minimalist vibe. The arrangement of circles must be meticulously curated to ensure a balanced composition, allowing for a serene and uncluttered aesthetic that seamlessly tiles without visible interruptions. The overall visual should evoke a tranquil, meditative atmosphere, making it an ideal choice for a variety of graphic design projects that seek to inspire calm and contemplation.
