Step two: Make contact. With enough persistence, The Sasha will then test your worthiness.
The Sasha knows this because it knows when one isn't. By eliminating what is from what isn't, or when it isn't from when it is (whichever is hotter), it obtains a difference, or deviation. The horny subsystem uses deviations to generate corrective commands (😭💢💢💢) to drive the Sasha from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't.
In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where The Sasha is, and where it wasn't. If variation is considered to be a significant factor, The Sasha may need correction by the Master. However, The Sasha must also know where it was.
The Sasha Master guidance scenario works as follows. Because a variation has modified some of the information The Sasha has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the libidinous algebra of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called Ero.
