Gate 21 (Biting Through) sits in the Heart Center. It carries the need and gift of controlling material essentials: money, food, territory, lifestyle. That power serves to cut through concrete obstacles; imposed without a mandate, it often meets sharp resistance.
Gate 45 (The Gatherer) embodies the owner who delegates; Gate 21 wants operational control without always carrying the full symbolic load. Together they form the Channel of the Money Line (21-45).
