In fact, a Statera cannot meditate because this is a training to calm the aura within aura veins of females. Males, regardless of the species, do not have aura veins; they possess an aura core.

It is common knowledge that the fundamental nature of Aura is chaos. All Aura found in the environment is chaotic, unstable, full of instability, and will of its own. This leads us to the next difference between Aura Veins and Cores. The second difference is that aura veins, present in females of any species, actively absorb and manipulate mana directly from the environment. In other words, females can manipulate the aura of the environment when they want to.
