There are 9 stages of meditation in Mahaprajnaparamita. It is the place that Gautama Buddha experienced. How can I experience it? In particular, how can we reach the limitless Space Levele, Limitless Conciousness Level, and Nothing ness Level?

What kind of meditation?
Unfortunately, this meditation does not remain in Japan. I reproduced. You can tell if the meditation I developed is genuine by experiencing guided meditation.

What is nine stages?
It's a Buddhist meditation. It is said to be a meditation done by the Buddha. This is different from normal meditation. It consists of nine stages: first zen, second zen, three zen, four zen, limitless Space Levele, Limitless Conciousness Level, and Nothing ness Level and non-thought non-thought. Go up the greed, color, and formless realms

In this meditation you go from the greed world, through the color world, past the formless realm, to the high boundaries of the two meditations. You will experience a territory that only Buddha could achieve in ancient times.

How to meditate it?
This meditation follows these in order. This is not normal meditation. This meditation goes up a special path. This is two to the left of normal meditation. So you take steps.

You go to the second part from the front in the space of meditation. You hit the blue dot on the left wall twice. Then, the part on the left side becomes stage 3. Meditate in that state.

Keep an eye on this position. Then all you have to do is raise the stage. You see the boundaries of the scriptures.

Meditate here and raise the stage. Then, you can see these boundaries. It is difficult to feel these boundaries by closing your eyes. Monks and intermediates should take a walk and look out during meditation. Then, the boundary spreads out in the field of view.

Boundaries of the nine
When you meditate, you can see the following. If you see these in order, the route is correct.

Adarsa-jnana (great-perfect-mirror wisdom, wisdom clearly elucidating all things) 大円鏡智
 The meditator sees this in stage 1. A large dark gray circle can be seen in front of you in the form realm. The movement of the limbs can be seen there. Old mirrors were made of copper or iron. It's close to that color.

Wisdom of equality 平等性智 
The meditator sees this in stage 2 (physiological desire). The outside of the big circle is bright. It is the color of the guardian spirit. This great circle is not dark. This situation is understood by comparing the things in front of us. The idea that clocks and figurines, hands and walls are equal comes to mind. If there are three or more things, three are not equal.

Wisdom of wondrous observation 妙観察智
 The meditator sees this in stage 3 (five senses). The big circle looks dark. Let's be quiet. When you are interested in something, you can feel your eyes focused and observed.

Wisdom of accomplishing that which is to be done 成所作智
  One sees this in a stage 4 (exercise). The big circle is black. While meditating, open your eyes and watch these. Immediately know the name of the movement. When the action finished, the name of the action is known.

Formless realm 無色界
This is a world without color. The field of view is bluish. The meditator experiences the four boundaries.

The state of unlimited sky  - 梵: Ākāśa-anantya-āyatana、巴: Ākāsānañcāyatana 空無辺処
The meditator sees this in stage 6 (reason). You see the blue world. You see the endless sky. You must check outside the house on a sunny day. You can't see this well from inside the house. It's easy here.

Unlimited Consciousnesses 梵: Vijñāna-anantya-āyatana、巴: Viññāṇañcāyatana 識無辺処
 You see here in stage 7 (society). Society consists of countless consciousnesses. You see a slightly blue world. You see a myriad of not-so-small consciousnesses. This state does not feel consciousness in things like animism.

Nothingness (ākiñcanya) 無所有処
  The meditator sees this in stage 8 (space). Looking inside the blue circle, it looks white and there is nothing. However, you can see your hands outside it. When you try to grab something, your hands disappears. It is the state where you cannot own anything.

Neither-ideation nor non-ideation (naivasaṃjñā-nāsaṃjñā) 非想非非想処
  The meditator sees this in stage 9 (face). The theme here is a square surface. Two picture frames are lined up. Looking at this from left to right, you can see a left frame, a left picture, a right frame, a left frame, and a right picture... You can't see anything in the frame, so it is "non". The picture reflects "thought", it is "idea". Then, it call 'non, idea , non,non,idea' in Japanese and Chinese. 

Saññā-vedayita-nirodha-samāpatti 想受滅
The meditator sees this in stage 10 (straight line). When you think of something, you move forward. That is received and disappear. You often feel it when you take a walk while meditating and look at the scenery.

 You feel the heart in this meditation. Going up from there, your heart's sensations disappear. You raise the stage.

Nirodha-samāpatti 滅尽定 
The meditator sees at stage 11 (points) the situation that "the mind and the ergonomics are extinguished for a fixed period of time." This is just past the sensation of the heart. You see blinking.

There is no explanation above from here on the stage in Buddhism. Even if you reach here, it is not a liberation. The stage above here is bluish. The theme of the stage seems vague. At stage 15, the world of Buddha can be seen and liberated.

Stage 12, object
This is also a pitch-black world. You see something that stretches straight. A rectangular parallelepiped floats in the sky.

Stage 13, plants
A white thing can be seen beyond the pitch-black world. You can see things that hang down in the dark world and things that grow up.

Stage 14, animal
The upper half of the white world can be seen. Things in the world are moving, and each one seems to be a living thing.

Stage 15, eyes
The world of Buddha can be seen in the distance. This is Nirvana. Big eyes look like the sky. The eyes can also be seen at the bottom.

Summary
The meditator sees what the Buddha saw during his early training in nine stages of meditation. If you go further, you will be released at stage 15.
