We consider the scenario, in which the light Higgs scalar boson appears asthe Pseudo - Goldstone boson. We discuss examples both in condensed matter andin relativistic field theory. In $^3$He-B the symmetry breaking gives rise to 4Nambu-Goldstone modes and 14 Higgs modes. At lower energy one of the four NGmodes becomes the Higgs boson with small mass. This is the mode measured inexperiments with the longitudinal NMR, and the Higgs mass corresponds to theLeggett frequency $M_{\rm H}=\hbar \Omega_L$. The formation of the Higgs massis the result of the violation of the hidden spin-orbit symmetry at low energy.In this scenario the symmetry breaking energy scale $\Delta$ (the gap in thefermionic spectrum) and the Higgs mass scale $M_{\rm H}$ are highly separated:$M_{\rm H}\ll \Delta$. On the particle physics side we consider the modelinspired by the models of \cite{dobrescu,Yamawaki}. At high energies the$SU(3)$ symmetry is assumed that relates the left - handed top and bottomquarks to the additional fermion $\chi_L$. This symmetry is softly broken atlow energies. As a result the only CP - even Goldstone boson acquires a massand may be considered as the candidate for the role of the $125$ GeV scalarboson. We consider the condensation pattern different from the one typical forthe top - seesaw models, where the condensate $< \bar{t}_L\chi_R >$ is off -diagonal. In our case the condensates are mostly diagonal. Unlike\cite{dobrescu,Yamawaki} the explicit mass terms are absent and the softbreaking of $SU(3)$ symmetry is given solely by the four - fermion terms. Thisreveals the complete analogy with $^3$He, where there is no explicit mass termand the spin - orbit interaction has the form of the four - fermioninteraction.
