  In objective gravitational reduction of the wave function of a quantum
system, the classical limit of the system is obtained in terms of the objective
properties of the system. On the other hand, in Bohmian quantum mechanics the
usual criterion for getting classical limit is the vanishing of the quantum
potential or the quantum force of the system, which suffers from the lack of an
objective description. In this regard, we investigated the usual criterion of
getting the classical limit of a free particle in Bohmian quantum mechanics.
Then we argued that how it is possible to have an objective gravitational
classical limit related to the Bohmian mechanical concepts like quantum
potential or quantum force. Also we derived a differential equation related to
the wave function reduction. An interesting connection will be made between
Bohmian concepts and gravitational concepts.
