Passages from The Mother [4]
“...it is only the very highest supramental Force... that can victoriously handle the physical Nature ...” [p. 2]. Is this idea to be found anywhere in the Upanishads or Vedas? What is there in this Force which can deal with Matter, and why cannot other forces do it — for example the occult vital forces that are used to produce kāya siddhi in Hathayoga?
The physical Nature does not mean the body alone but 
the phrase includes the transformation of the whole physical mind, vital, 
material nature — not by imposing siddhis on them, but by 


 creating a new physical nature which is to be the habitation of the 
supramental being in a new evolution. I am not aware that this has been done by 
any Hathayogic or other process. Mental or vital occult power can only bring 
siddhis of the higher plane into the individual life — like the Sannyasi who 
could take any poison without harm, but he died of a poison after all when he 
forgot to observe the conditions of the siddhi. The working of the supramental 
power envisaged is not an influence on the physical giving it abnormal 
faculties, but an entrance and permeation changing it wholly into a 
supramentalised physical. I did not learn the idea from Veda or Upanishad, and I 
do not know if there is anything of the kind there. What I received about the 
Supermind was a direct, not a derived knowledge given to me; it was only 
afterwards that I found certain confirmatory revelations in the Upanishad and 
Veda.
