  Context: The unification scheme of Seyfert galaxies hypothesizes that Seyfert
type 1s and type 2s are intrinsically similar and the observed differences
between the two subtypes are solely due to the differing orientations of
toroidal-shaped obscuring material around the AGN. In the framework of the
unification scheme, both the Seyfert subtypes are expected to show similar
intrinsic nuclear properties, such as the absorption-corrected AGN X-ray
luminosity, bolometric luminosity, accretion rate and the mass of the
supermassive black hole. Aims: To test the predictions of the Seyfert
unification scheme, we make statistical comparison of the distributions of: (i)
the absorption-corrected 2.0 - 10 keV X-ray luminosities, (ii) the bolometric
luminosities, (iii) the black hole masses and, (iv) the Eddington ratios, of
Seyfert type 1s and type 2s. Methods: We use an optically selected Seyfert
sample in which type 1s and type 2s are matched in properties that are
independent to the orientation of the obscuring torus, the AGN axis and the
host galaxy. Results: The distributions of the absorption-corrected 2.0 - 10
keV X-ray luminosities, the bolometric luminosities, the black masses and, the
Eddington ratios are statistically similar for the two Seyfert subtypes,
consistent with the orientation and obscuration based Seyfert unification
scheme. The Eddington ratio distributions suggest that both the Seyfert
subtypes are accreting at sub-Eddington level with wide span of Eddington
ratios i.e., 10^-4 - 10^-1.
