It is only the Sahasrara has to grow, not the Spirit. The more sensitive the Sahasrara is, the more it receives the spiritual qualities of the Spirit. Actually the peace is felt in the Sahasrara. The bliss is also felt in the Sahasrara because that is the brain and the brain is the epitome of our nervous system, central nervous system, of consciousness itself.
Nirmala SrivastavaWhen you start witnessing something without thought, there is no obstruction for absorbing the knowledge about that thing because there is no thought. It's complete absorption which takes place. And then it manifests. This is how the Divine Power works within us. So with our gravity, what we do is to touch that depth within us, which can carry the Divine Power and manifest.
