Roland Albrecht:
...before Otto v. Gericke (1602-1686)  invented the vacuum, there was talk about the NOTHING. 
But what is NOTHING? The NOTHING lets minds drift apart: 
Master Eckehard: 
"To lapse into the highest spirit is essentially like a fall into the depth of NOTHING. "

Leonardo da Vinci: 
"NOTHING has no middle and its borders are the NOTHING. Amongst the important issues to be found amongst us, is the being of NOTHING the 
largest." 

Plett 
"it is nice when something empties itself in the mind.....i am presenting here my version of the tibetan prayer wheel. 
Whilst I am turning it I say again and again , not too fast: vac, vac........ 
the mind is empty in a wonderful  way - and all of 
a sudden the whole life surges above it, like a giant advertising area." 

E.A.Sarau:
'the athmosphere is under earth's gravity, by that we have the pressure 1000gramms/square meter. This pressure exists everywhere. Mr. Ottov.Gericke has 
thought out a pump with which one can draw gases out of a space, out of the socalled halfball of Magdeburg, which is exhibited now in the deutsche museum in munich. with this pump air as sucked out of the ball. 
There is no absolute vacuum in a technical sense. One feels differences in pressure. Outside the ball there is a pressure of one bar, inside it is .7 bar, so inside there is underpressure. If the ball's tap is opened pressure equality has once again been established." 

Elke Suhr :
Plotin: The spirit which has fallen off the Universal One reaches its reunification with it by ecstacy. 
El Greco:. "ascension of mary" (jahr) in its special manner gives us an image of this. 
According to Herman Schmits (Philosoph).this elevated spiritual state has to be aimed for, but in human live can not be reached in continuance, but is rather part of swinging inbetween extreme poles. Based on this thought the vacuum would subjectively be a state of independence of time and space.....a state of separation, of chaos, of absence of thoughts, poor understanding.
