LOL. You really touched my soul with that brilliant response!
BTW, that intelligence which you call pure space IS THE SOUL, part of which resides in every living being! When you achieve NIRVIKALP SAMADHI, google it, your part of that whole PURITY becomes one! That's what every yogi wants to achieve, don't they?
BTW, the PART is never bounded by any type of walls.. It's MAYA which defines the state of individual souls, which are parts of the WHOLE, as people know them -- as individual souls.
I will tell you about it as a story: So all ears/eyes to it

:
It's like taking sea water and filling it in glass vials, and then dropping all the vials back in the ocean... the ocean water filled in each vial/glass bottle is the soul as we know it. As it sinks to the bottom, it first enjoys the surrounding and sees plenty of young bottles around him, in the seeping sunlight. He enjoys and plays with the other bottles. Then later he sinks further and the pressure too increases on the body of the bottle.
Now he sees some bottles are breaking up due to the pressure, sees some already broken bottles, and he begins to feel fear -- of the unknown, of destruction, of death.
Death comes. The body of the bottle begins cracking and breaking. The bottle really feels the last moments and it panics. The water inside the bottle then escapes out of the open holes and ---well, mixes with the outside water/ocean! That moment, it (the water which was inside the bottle and is now outside) knows that all the while it was exactly a part of the outside water/ocean! He was exactly the same as the outer ENTITY! He was all the time ONE with the INFINITE!
It took "a death" for the water inside the bottle to understand the truth! Some know the TRUTH when they are still inside...

That's the soul and the infinite for me! Same for you too?
Take it or leave it, dude! It's just a story! lol
BTW you should meditate on all the opened chakras ALL at once! Remember, you'll be shocked if it is achieved! And then, you meditate on the infinite chakra of which all your (opened or closed or whatever stage they are) chakras are a part! A very hard concept even to visualize for most...AND, HINT: there is absolutely no need to spend life cycles to do it. Nirvikalp Smamdhi can let you achieve the ultimate of the samadhis/meditations. But it's very difficult to achieve even a few seconds of the actual stage. Your mind is made just to break your nirvikalp samadhi, especially if you're trying to achieve anything else other than the ultimate.
