Shevirat ha-kelim, or 'the breaking of the vessels,' refers to a pivotal concept in Kabbalah that describes the process of divine emanation and the resulting fragmentation of spiritual vessels. This idea illustrates how the initial act of creation led to the vessels meant to contain divine light becoming shattered, resulting in the scattering of holiness throughout the world. This fragmentation is essential for understanding the nature of existence and the role of humans in restoring balance by gathering these sparks of light.
