VLBI observations have revealed that OH/H2O maser sources are the aggregations of blobes with the sizes of a few A.U., spreading over the distance of several 1017 cm. From the standpoint of masing mechanism, especially for the hydroxyl case, we will argue that the blobes correspond to proto-stars in the stage of forming an opaque core, and the aggregations correspond to proto-clusters.
