  I summarize the status of neutrino oscillations that follow from current
data, including the status of the small parameters ratio of
solar-over-atmospheric splitting and $\sin^2\theta_{13}$ characterizing the
strength of CP violation in neutrino oscillations. I briefly discuss the impact
of oscillation data on the prospects for probing the absolute scale of neutrino
mass in neutrinoless double beta decay. I also comment on the theoretical
origin of neutrino mass, mentioning recent attemps to explain current data from
first principles.
