First off, you need to understand that there is a very complex science behind this. No matter what you do, you cannot escape physics. But even with the "limits" of physics, even some amazing unbelievable things can happen. I will answer a few questions that I am commonly asked.
Q: Do you get bigger or smaller when you shift?
A: No, it is not physically possible to change in size in the quick shifts I am going into, and wolves have the same ranges of body mass, so it is unnecessary. The law of conservation of mass states: Matter cannot be created nor destroyed in a chemical reaction. This means that you cannot change in size unless you find a way to draw on a source of matter, and as far as I know, there is no way.
Q: What happens to your clothes when you shift?
A: Well, most prefer to remove their clothes prior to shifting. If you do not, you will simply have to find a way to remove your clothes when you are in wolf form.
Q: When you shift, do you become a full wolf, or a hybrid?
A: As far as I have seen, everybody becomes a full wolf, but in a partial shift, which is a rare incident, or can be performed voluntarily by terminating a shift while in the transition (which is quite a bit harder than it sounds) will result in a partial shift, which will leave you in whatever hybrid stage you were in at the instant of termination. You can also shift individual body parts by only focusing on them.
Q: Is there a limit of time that you can remain in wolf form?
A: Technically, yes. Each person's limit varies on how much practice they have had. The reason for this limit is because the longer you remain a wolf, the deeper established your wolf form becomes, which means that it gets harder to change back the longer you remain in wolf form. The consequence of exceeding the time that you can power is simple: you lose the ability to change back. You basically get "stuck" as a wolf for the rest of your life, or until you can overwhelmingly pull through (rare). This point at which you should not pass is called the point of no return. Usually for a beginner it is about an hour, however for very experienced shifters, it can extend into a week. Never pass the PNR. That is an important warning.
Q: When I shift, will I still have my human mind?
A: Yes and no. Yes you will remember everything, and be in control. No, your mind will be quite changed. You will have the deep end of instincts and heightened senses as well as reaction. There is a certain situation that can cause you to temporarily lose your entire human function. That is called "possession". It is when your mind rejects it's human side entirely. There are 3 degrees of possession. 1st degree: Short loss of humanity (up to 1 minute), 2nd degree: Temporary long loss of humanity (1 minute or longer), and 3rd degree: permanent loss of humanity (permanent). Possession must be predicted before it occurs, because if you reach 3rd degree possession, you will have absolutely no human left in you. To predict this incident before it happens, there are symptoms you should be aware of: inability to control M-shifting, short attention span, overwhelming wolf instincts, occasional feeling or desire (like an addiction) to shift into a wolf, involuntary P-shifting, extreme loss of energy during p-shifting. If you have any one of these symptoms, be cautious that you do not lose focus while shifting, if you have more than 2 of these symptoms, you will very likely become possessed if you lose focus during a shift. This high risk can be reduced by practicing focus. It will always be a danger though.
Q: Can you become an animal other than a wolf?
A: Some of them, yes. Others require long term shifting (I don't describe it because it is unnecessary to become a wolf, and it requires total loss of ability to change back.) The ones that do not require long term shifts are the ones with same mass range as us (they can weigh the same as you)
AND LAST BUT NOT LEAST, THE ONE THAT I GET ASKED MORE THAN ANY OTHER QUESTION: HOW TO SHIFT
I will describe the method for all forms of shifting. By popular request I will include not only rapid shift, but my general concept of long term shifting. If you know an animal form eligible for the rapid shift, then substitute the word "wolf" with "_whatever your animal is_"
There are 2 classes of shift, M and P. As you might already know, M-shift is Mental shift, and P-shift is Physical shift. The M-shift is where you induce instinct, thought pattern, and the base around which the P-shift is built. The P-shift is the actual change of the form of the body. There are 3 different subclasses of P-shift. They are Practice, On-Spot, and Long-Term. Before any of these, you must achieve an M-shift, and then, the first subclasses available are practice and long term. After practice, comes On-Spot, which is the true mastery of the P-shift. Long term is not a mastery, but a commitment. If you long term shift, you will never again be human, and once you have unlocked it, there is not turning back. Now that I have covered the basics, we are ready to proceed to the instructions, starting with the M-shift.
Warning! Shifting is a life change, it is not something to mess around with. Certain parts and consequences are irreversible. Do not attempt unless you are absolutely sure of what you are about to do. I reserve no responsibility for any action that you might take. Be aware of my warning. This REALLY WORKS when performed as instructed!
To M-Shift, there is a thing I like to call the 3IA of M-Shifting. Inspiration, Investigation, Imagination, Application. Those are all the steps to a successful M-Shift. Inspiration: You need to inspire yourself. Keep some pictures or other representation of a wolf nearby or with you at all times, and try to keep yourself thinking of wolves nonstop. At around the same time, you need to Investigate. Investigation: You need to find as much information about wolves as you can, and quiz yourself. Make yourself as much of a wolf expert as you can. After you are an "expert" you need to use all that knowledge you gathered and imagine it. Imagination: You need to draw on the behavior, minds, and instincts of wolves, and simply imagine yourself (to the point that you believe it) as a wolf, but not physically, mentally. Continue doing this until you are not only a wolf enthusiast and expert, but also a wolf at mind, so much that you feel that you are one at points, this means that the wolf side has taken over your mind. This is not a switch on and off thing. The M-shift is permanent, but it can be controlled so that you can fit in in human society. Once you M-shift, your mind is set on a permanent course becoming a wolf mind. It is irreversible, and can be set off involuntarily. This will definitely change you forever.
The next stage I will talk about is the Practice P-Shift stage. The alternate stage that opts-in here is the Long-Term Shift, which is 2 paragraphs down. The starting point of the practice P-shift is completion of the M-shift. Once that is complete, you must once again draw on the expert knowledge that you obtained in the Investigation part of the M-shift. You need to be able to picture the physical aspects of a wolf, AS MUCH AS YOU CAN POSSIBLY GET, and bring it to mind again. You must then use the skill gained in the Imagination part of the M-shift. You need to first fire up that wolf mind and relieve all restraints and "release your inner wolf" in a sanctuary (somewhere that you can be alone, relaxed, and free of all distractions.) Then you need to get relaxed as deeply as possible, and gather as much focus as you can on what it would look like and feel like to be a wolf for a second, now, fire up that wolf mind all the way until you feel you are a wolf again. Now, imagine your human body as "what I would look like IF I was a human" and work from that, and how it would feel as a human, and what it would look like, then work on to what it would feel and look like to shift into a wolf. Imagine it as VIVIDLY as possible using all senses. Keep practicing, it might not work the first time, I also recommend focusing on one body part at a time as you practice it, because you will get individual parts easier. Eyes, teeth, ears, paws, those are the easiest few. The tail comes in just after these. Work towards your end goal with PATIENCE. If you are impatient, you will not get any results. Usually a full shift takes 2 weeks to 4 months to achieve. It depends on the concentration of wolf blood in you, the more you practice, the more concentrated it becomes. You definitely don't want 100% though (that only happens after PNR, and 3rd degree possession). Once you achieve a shift, I call the point at which you shift, the barrier. The barrier is also called the "sneeze" by some, because the nature of the barrier is exactly like a sneeze. It begins with a strange sensation that rushes across you, and becomes a burst that you cannot control. When you reach it, you will feel a sensation like a cozy warm feeling, then a feeling of energy surging through you (not painful), that soon becomes a feeling of clenching and flexing all over your body, and a strange feeling that everything your body is made of is changing. During this, your body involuntarily moved as if you are being controlled, and it leaves you helpless to control your own body, this barrier lasts anywhere between 5 and 50 seconds. It is important that once you reach the barrier, you do not panic, or you will terminate the shift, and nothing will happen. You need to just be relaxed as a rock and let the shift take it's course. Once you do, you will become a wolf. So at this point it is important to know how to shift back. In the first few shifts, falling asleep is usually enough to end it, but if you aren't tired, remember that staying a wolf on the first few shifts for longer than an hour can result in PNR passing, and being "stuck" forever. So the other method is to P-shift back, imagine yourself returning, you might need to use more strength and focus the longer you stay. Be aware of that. It is a more simple reverse method of P-shifting to turn yourself back.
After the Practice shift, you are ready to work on the On-Spot P-Shift. Take note that this one is the one with the highest danger factor for those with possession. In this one, you just need to practice fully flaring your m-shift, and focusing hard enough to induce a full shift while you are not in controlled circumstances. Best methods of training involve doing this while standing up. Practice avoiding distractions, flaring your focus, flaring your M-shift, and quickly P-shifting. It is important to emphasize focus, and dropping your humanity to the point you know you are a wolf on a moments notice. String everything together and practice to P-shift on a moments notice in a distracting and stressful environment. That is the On-Spot shift.
***This is long term shifting, it is the shift that you can never return to human form, which you can use to become almost any animal, it is not recommended. DO NOT EVER ATTEMPT UNLESS YOU ARE READY TO GIVE UP YOUR ENTIRE HUMAN LIFE FOREVER. Now that you have been warned, this is just a concept, I cannot guarantee it works, because anybody who used it is no longer a human. The data I compiled is well passed in archives. It is not a common one, but under study, I find that it could work if performed properly. The Long-Term shift is long term in 2 ways. It lasts until you die, and it takes a relatively long time to be complete. First, you need to have some form of that animal's genes in you somewhere, and they must be in an active cell. You just repeat the actions in the M-shift, and Practice P-shift, but in the practice P-shift, you must focus day after day, and expect very tiny results. Eventually it will set you on a frictionless course to permanently becoming that animal. This one can work for animals of different masses, because the time frame allows you to gain or lose significant amounts of mass. This one is absolutely irreversible and inevitably results in possession.
