Stage of my personal practice This  time when  the controller  of the  breath  disappears  thoughts  too disappear cittarupa  stop by presenting  a line across  and the top of it there is a picture  of a person. After a minute breath  appeared. And there was no observer  too at that time. What is the meaning of the cittarupa  which appeared and what is the stage?
You can find some advice from Ajaan Fuang on this page:


  § When Ajaan Fuang taught meditation, he didn't like to map things out
  in advance. As soon as he had explained the beginning steps, he'd have
  the student start sitting right in his presence, and then take the
  steps back home to work on there. If anything came up in the course of
  the practice, he'd explain how to deal with it and then go on to the
  next step.
  
  Once a layman who had known more than his share of meditation teachers
  came to discuss the Dhamma with Ajaan Fuang, asking him many questions
  of an advanced nature as a way of testing his level of attainment.
  Ajaan Fuang asked him in return, "Have you had these experiences in
  your own meditation yet?"
  
  "No, not yet."
  
  "Then in that case I'd rather not discuss them, because if we discuss
  them when they're not yet a reality for you, they'll just be theories,
  and not the real Dhamma."
  
  § One meditator noticed that his practice under Ajaan Fuang was making
  quick progress, and so he asked what the next step would be. "I'm not
  going to tell you," Ajaan Fuang said. "Otherwise you'll become the
  sort of amazing marvel who knows everything before he meets with it,
  and masters everything before he's tried his hand. Just keep
  practicing and you'll find out on your own."
  
  § "You can't plan the way your practice is going to go. The mind has
  its own steps and stages, and you have to let the practice follow in
  line with them. That's the only way you'll get genuine results.
  Otherwise you'll turn into a half-baked arahant."
  
  § "Don't make a journal of your meditation experiences. If you do,
  you'll start meditating in order to have this or that thing happen, so
  that you can write it down in your journal. And as a result, you'll
  end up with nothing but the things you've fabricated."
