Mandala Psicodélico del Zodiaco Cósmico

A square, perfectly centered psychedelic sacred-geometry mandala on a black cosmic starfield background. The composition is radially symmetrical with 8 major pointed lotus-petal arms and a kaleidoscopic crystalline structure glowing like neon stained glass. In the exact center is a black circular medallion filled with tiny gold stars and a delicate golden constellation outline of [Taurus bull]. Surrounding it is a sharp geometric mandala formed of translucent triangular and polygonal facets with bright thin luminous outlines and small arrow-like markings. The geometric bands display a vivid rainbow progression of [electric violet, cobalt blue, emerald green, yellow, orange, and red], mirrored symmetrically across all quadrants. The outer ring features 8 large dark purple lotus petals filled with swirling galaxy spirals in magenta, orange, green, and blue, branching lightning filaments, and glittering star dust. Radiating outward into the deep black space are angular shards, zigzag crystal formations, and comet-like splinters. Crisp luminous edges, dense fractal micro-details, glittering starlight, high contrast. No text, borders, watermarks, or human figures.
