  We use the auxiliary fields and (excited-) de Sitter solutions to study the
standard power spectrum of primordial fluctuations of a scalar field in the
early universe. The auxiliary fields are the negative norm solutions of the
field equation and as it is shown, with a fixed boundary condition, utilizing
these states results in a finite power spectrum without any infinity. The power
spectrum is determined by the de Sitter solutions up to some corrections and
the space-time symmetry is not broken in this point of view. The modulation to
the power spectrum is of order $ (\frac{H}{\Lambda})^{2} $, where $ H $ is the
Hubble parameter and $ \Lambda $ is the energy scale, e.g., Planck scale.
