DESCRIPTION:We introduce a generic mechanism that can extend the effects o
 f relic anisotropies at the beginning of inflation to relatively much shor
 ter scales in density perturbations. This is induced by non-Bunch-Davies s
 tates of the quantum fluctuations\, and can show up in the non-oscillatory
  components of the density perturbations. This mechanism works for general
  forms of anisotropies\, and\, to illustrate it\, we use an example of rel
 ic vector field. The detailed scale-dependence of these anisotropies can b
 e used to probe the initial quantum state of our universe.
