Vitarags have described 3 types of body - gross body, electrical or vitality body and causal body.
Modern science have tried to study first two of it, third being very subtle is out of reach of
it.

(b) Cerebrospinal fluid is secreted into the ventricles and flows throughout the subarachnoid space where it cushions the central nervous system.

(d) Cerebrospinal fluid is reabsorbed back into the blood at fingerlike projections of the arachnoid membrane called villi.
