This group is modeled after the Hyperbolic Time Chamber that Gohan and Trunks train to defeat Majin Buu in Dragon Ball Z.
In the Hyperbolic Time Chamber, gravity is ten times that of Earth. Which means, the pressure is on. This place is meant for those who are willing to face truths that could be painful to realize. It is going to take perseverance.
Time is also altered in the Chamber. One day outside is the same as one year inside. When we are faced with things that make us feel the emotions we are trying to hide (whether consciously or subconsciously) like shame, or guilt, time can stand still. But it’s there the choices are made. How you deal with something and the choices you make build or degrade your character.
And let’s not forget the reason why Gohan and Trunks trained there, despite the grueling conditions of the gravity and the long years, and the extreme conditions. To protect, out of love. They had to become strong and better themselves, for themselves, but also for those around them.
There is no magic cure to your problem. There is only time, and choices. How you use them is up to you.
