It follows immediately from the fact that formula_51 satisfies the guiding equation that also the configuration formula_48 satisfies a guiding equation identical to the one presented in the formulation of the theory, with the universal wavefunction formula_25 replaced with the conditional wavefunction formula_54. Also, the fact that formula_55 is random with probability density given by the square modulus of formula_56 implies that the conditional probability density of formula_48 given formula_49 is given by the square modulus of the (normalized) conditional wavefunction formula_59 (in the terminology of Dürr et al. this fact is called the "fundamental conditional probability formula").
