Higher Centers are always trying to change us
If you take things as you have always taken them, nothing new can form itself, but if you take life from what the Work teaches and take yourself in a new way, you will make a new pattern, new associations in the frontal lobes if you like, and these will connect with Higher Centers. If your aim is right this will happen gradually, but if your aim is a life-aim, a purely ambitious aim, you will not form any new patterns, but just ordinary commonplace ones.
Only new mind reaches Higher Centers
The Work is to get the psychological world rightly adjusted so that it transmits Higher Centers. We may in life conceal our psychological thoughts and feelings but the Work is another force not of life, and from that we can conceal nothing that is psychological.
