In the Masnavi, Rumi uses the metaphor of the Vat of Jesus (Khom-e Isa) to symbolize divine unity and the purification of the soul. Drawing from Islamic folklore which depicts Jesus as a miraculous dyer who could dip differently colored garments into a single vat and extract them all purely white or uniformly colored, Rumi contrasts the multiplicity of outer religious forms with the singular truth of spiritual realization. The 'hundred-colored' garments represent the various superficial methods and dogmas, while the 'one-coloredness' of the vat represents spiritual purification and the transcendent, unified truth (often associated with 'sibghat Allah', or the dye of God).
