The utility of psychic experiences and knowledge of the invisible worlds as of
other yogic experiences is not to be measured by our narrow human notions of what may be useful for the present physical life of man. In the first place
these things are necessary for the fullness of the consciousness and the completeness of the being. In the second
place these other worlds are actually working upon us. And if you know and can enter into them then instead of
being the victims and puppets of these powers we can consciously deal with, control and use them. Thirdly, in my
yoga, the yoga of the supramental, the opening of the psychic consciousness to which these experiences belong is
quite indispensable. For it is only through the psychic opening that the supramental can fully descend with a strong
and concrete grasp and transform the mental, vital and physical being.
There is no fixed rule in such things. With many the descent comes first and the ascension afterwards, with others it is the other way; with some the two processes go on together. If one can fix oneself above so much the better. I have explained to you why it did not happen.
