Harish-Chandra defined a homomorphism $\delta : \mathcal{D}(\mathfrak{g})^{G}\to \mathcal{D}(\mathfrak{h})^{W}$ of algebras of invariant polynomial differential operators. The construction and existence of $\delta$ are somewhat mysterious. We show how $\delta$ naturally arises when one considers matters in the context of $\mathcal{D}$ -modules.
