Sometimes it's very hard to turn off my brain especially when I have an eighteen hour day. I try to stop working by 10 or 11pm but you know sometimes there is nothing I can do about it.
The mind is a finer body, and resumes its functions of feeding, digesting, absorbing, excluding, and generating, in a new and ethereal element. Here, in the brain, is all the process of alimentation repeated, in the acquiring, comparing, digesting, and assimilating of experience. Here again is the mystery of generation repeated.
Don't we introduce time as a means of becoming more evolved? The brain has evolved but is there evolution inwardly? Can the brain dominated by time not be subservient to it?
You have heard that Christ said, 'My words are spirit and they are life'. So are my words spirit and life; they will burn their way into your brain and you will never get away from them!
If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
