Today, the Kaaba is covered in a black cloth, which wonderfully represents the endless and transcendent nature of God. Black is not the absence of color, but rather the outcome when all color is absorbed without reflection. Similarly, God unites all diversity within His singularity. The Kaaba is empty inside, signifying that God cannot be captured or contained in any finite form. The importance of not being too literal when conceptualizing the Kaaba is perfectly illustrated in a story of Mullah Nasruddin, who traveled to the holy city of Mecca for the Hajj pilgrimage.
