Quick Definition: The process of understanding the principals behind a seduction technique, both consciously and unconsciously.
This is the mental metaphor for the solid understanding of seduction, more than just the memorization of words. Repetition is the father of learning. This process happens over a period of time, depending on how often the PUA practices the new skills he has learned.
For example, a newbie who attended a weekend bootcamp may take the next 1-2 years on and off to internalize the things he has learned in game. On the other extreme, the PUA who leaves his job to study under Project Rockstar and lives with other mPUAs and aspiring PUAs will improve dramatically and being to internalize a lot of the concepts within a few weeks. This is because he is living the life of a player 24/7.
Whatever skill you learn, it is important to reach the repetition stage where the memories of the skill are deeply ingrained into your long term memory cortex. This way, once learned, you can always recall and use the skills you earned the right to use for the rest of your life.
