  We suggest that the Large Mixing Angle MSW solar solution, whose unique
physical status is confidently supported by the recent results from KamLAND
experiments, gets its justification in the fermion universality, interpreted
for neutrinos and charged leptons in a straightforward way, most readily in the
framework of seesaw mechanism. To this end, we consider an explicit seesaw
model, where Dirac and (righthanded) Majorana neutrino masses are
simultaneously measurable, and {\it both} are conjectured to be proportional to
charged-lepton masses. However, the LMA solar solution is {\it also} not
inconsistent with the simple option, where neutrinos are Dirac particles
carrying masses proportional to those of charged leptons.
