The widely heralded and remarkable progress in cosmology leading to the emergence of a 'standard cosmological model’ has relied on certain key assumptions at various levels. I review work along multiple facets, largely, from the research program of my group at IUCAA, that have all attempted to adopt an agnostic approach in drawing cosmological inference independent of such assumptions, in the context of the exquisite observations of the Cosmic Microwave Background CMB anisotropy by Planck. I dwell on the enigmatic Cosmic Hemispherical Anisotropy that continues to challenge our understanding of the Universe.
