Seventh (7th) Astral Dimension / Plane
The 7th Division or Plane is the "lowest dimension" of the astral world. This Plane is known as Avichi. Here, is where the lowest, and the gross and unrestrained passions exist, and the astral material of the astral body is comprised of much the same dense matter, too. This plane is hell to the inhabitants who dwell here, and if there is such a place as Hell, this would be it. Why?
Because this is a place where the inhabitant's desires cannot be satisfied because they do not have a physical body to satisfy them. They can see but they can't touch! Thus, their inability to satisfy their desires is torturous. Perhaps this is the hell-fire Hell Christianity preaches about? In any event, unlike the Christian belief, according to Theosophy, the tortures of Avichi are NOT eternal but eventually dissipate as the desires (through prolong striving without fulfillment) gradually die away. Perhaps this place can better be described as a Purgatory state? More on this later.
Note: When we (our physical bodies) die, usually, most ordinary individuals do NOT wake up on this (7th) plane, but on one of the three higher planes - 6th, 5th or 4th plane.
On the lowest subdivision, you are surrounded by a thick, sticky, foggy atmosphere. You have an unpleasant feeling about this region. Amidst this dimly lit region, you perceive countless human forms of the most repulsive appearance. They are the disembodied souls in the astral body, living on the low plane they descended AFTER they awoke from their very brief astral sleep.
Through the enveloping fog, you become conscious of the physical, material world, which appears like a backdrop. Although it appears detached and removed in space, to these lowly creatures, the two planes seem blended together, in fact, they appear to be living among the people of the lowest phases of earthly life.
But these poor souls can only see, or watch these low earth scenes; they cannot participate, nor make their presence felt. The very sights they enjoyed so much while in the flesh (glutinous eating, drunkenness, obsessive gambling, debauchery and brutality, etc.) is now merely lust to their eye and a thorn in their flesh. This is their HELL. The lack of a physical body to enjoy these physical pleasures is torturous hell to them.
These degraded souls are "punished NOT FOR their sins, BUT BY their sins."
