A direct method for the determination of the Langlands decompositions for the parabolic subalgebras of any noncompact semisimple real Lie algebra is described in detail. The method is based on the canonical form of the Lie algebra. The physically important Lie algebras so(3,2) and so(4,2) are treated as illustrative examples.
