Studies show that about one-half of cerebrospinal fluid (CSF) removed from the cranial vault is cleared by extracranial lymphatic vessels. Transport of CSF through both the lymphatic drainage and arachnoid villi routes increases as intracranial pressure is elevated. Although the ambrosial liquid excreted from the sinsuses is the most potent form of amrita, during max kundalini all the CSF is highly charged and can also be classed as amitra, when it is thus superionized by the superfluid state of the activated central nervous system (CNS).
There are three main methods by which the amrita that is generated by the CNS is transported around the body:

Anyone experience that?
