  Various hints on the neutrino masses namely, ({\em i}) the solar neutrino
deficit ({\em ii}) the atmospheric neutrino deficit ({\em iii}) the need for
the dark matter and/or ({\em iv}) the non-zero neutrinoless double beta decay
collectively imply that all the three neutrinos must be nearlty degenerate.
This feature can be understood in the left right symmetric theory. We present a
model based on the group $SU(2)_{L}\times SU(2)_R\times U(1)_{B-L}\times
SU(2)_H$ which can explain the required departures from degeneracy in neutrino
masses and large mixing among them without assuming any of the mixing in the
quark or charged lepton sector to be large as would be expected in a typical
$SO(10)$ model.
