  Using the supersymmetric (SUSY) invariant restrictions on the (anti-)chiral
supervariables, we derive the off-shell nilpotent symmetries of the general one
(0 + 1)-dimensional N = 2 SUSY quantum mechanical (QM) model which is
considered on a (1, 2)-dimensional supermanifold (parametrized by a bosonic
variable t and a pair of Grassmannian variables \theta and \bar\theta with
\theta^2 = \bar\theta^2 = 0, \theta\bar\theta + \bar\theta\theta = 0). We
provide the geometrical meanings to the two SUSY transformations of our present
theory which are valid for any arbitrary type of superpotential. We express the
conserved charges and Lagrangian of the theory in terms of the supervariables
(that are obtained after the application of SUSY invariant restrictions) and
provide the geometrical interpretation for the nilpotency property and SUSY
invariance of the Lagrangian for the general N = 2 SUSY quantum theory. We also
comment on the mathematical interpretation of the above symmetry
transformations.
