A new interpretation is introduced for MOND based on the Sciama's interpretation of Mach principle and an Unruh like effect, in the context of a generalized equivalence principle. It is argued that in a locally accelerated frame with acceleration a the appearance of a Rindler horizon may give rise to a constant acceleration a0 as the local properties of cosmological horizon or Hubble length. The total gravitational acceleration inside this frame becomes the combination of a with a0. For a≫ a0, the conventional gravitational mass mg interacts with the dominant acceleration as mg a and application of Sciama's interpretation leads to the standard Newtonian dynamics. For a≪ a0, however, a reduced gravitational mass mg interacts with the dominant acceleration as mg a0 and the application of Sciama's interpretation on this reduced gravitational mass leads to MOND. This introduces a third proposal for MOND: \it The modification of gravitational mass.
