  By exploiting the supersymmetric invariant restrictions on the chiral and
anti-chiral supervariables, we derive the off-shell nilpotent symmetry
transformations for a specific (0 + 1)-dimensional N = 2 supersymmetric quantum
mechanical model which is considered on a (1, 2)-dimensional supermanifold
(parametrized by a bosonic variable t and a pair of Grassmannian variables
(\theta, \bar\theta). We also provide the geometrical meaning to the symmetry
transformations. Finally, we show that this specific N = 2 SUSY quantum
mechanical model is a model for Hodge theory.
