We obtain exact equation for the condensate wave function of the Bose liquid. Unlike the approximate Gross-Pitaevskii equation [1] it reflects the infrared anomaly -the special manifestation of the broken gauge symmetry which is connected with ,ero and thermal vibrations [2][3][4]. We find the exact
