Constitution always stands for the society and never for an individual.It stands for supremacy of law. It is conceived democratically.
Constitution stands for law and everything that is for law and it stands against every thing that is against law. Rule as per law, in the name of law,and get yourself ruled through that law which you yourself created.
 Constitutionalsm,thus is the sum total of all those activities that lead to governance of a nation democratically and only as per law.It controls the concept of absolute state, absolute power, and absolute governance. It divides power or regulates the source of authority.
Constitutionalsm,controls overflow of power and there by is the safest safeguard against exploitation and autocratic despotism.
