Gevurah

Severity / strength — anatomical left shoulder

Gevurah — strength as the power of restraint, judgement, and limit. Associated with Isaac and the left arm of Adam Kadmon. It is the discipline that gives form to Chesed's flow; without it, kindness dissipates and structure cannot hold. In the kabbalistic theodicy Gevurah is also the root of stern judgement, and unbalanced Gevurah is the structural origin of the sitra achra (the 'other side', the Qliphoth). Isaac's binding (the Akedah) is read as the paradigmatic Gevurah-event.
