When starting out in submission, there are a lot of roads you can choose and so many people direct novices to training and need to be trained. Most of these novices then seek out a Master or Dominant to train them. This concept that the Dominant can teach the submissive more about surrender is a myth. Dominants only provide submissives with the tools they need to then seek further surrender.
My stand on this a stepping off point from the video post about Slave Training. I said in that post that training was everything that you do for your Dominant when directed to do so in a certain manner. That is partially correct. Yes, in a basic form that is training in a relationship, but it does not work towards a submissive's ultimate goal of deeper surrender. If you want to deepen your surrender then you need to look inside yourself and learn what it really is to be submissive, find that core of desire within yourself and fan the flames. A Dominant does not know how to do this and can not help you get there. This is your personal journey; the journey inwards.
Think about how many times you've thought that your Dominant (or any Dominant) just doesn't understand where you are coming from, or how hard it is to submit all the time. That's exactly it. A Dominant can not get in touch with their submissive side, and believe me, everyone has one. If they are in their Dom Hat, They can think intellectually about your submission, but they can't touch on the emotional, passionate side of your submission - the part that drives you to do things with joy and love and fulfillment.
Dominants that may have submitted first in their explorations or switches have a different but similar issue. They may know what it's like, or what an experience did to them, but they still can't help you. What they felt or dealt with as far as struggle will be different for them than for you. The advice they may give you is based on how they interacted with the experience. Even if they felt deep in submission during that time, once they put that Dom Hat back on, they can't get in touch with it. It's a road block.
What can you do to improve your submission if you can't be trained in it by your Dominant? Your Dominant is still a valuable tool for slave training and we can use them as a tool for our own development. Take the rules and orders they give us, how do they mold us if we are also seeking a deeper level of submission. Can we make them a learning experience to be able to focus deeper on our own? Most of the time, Dominants allow and encourage submissives to speak to other submissives. There is an intelligent reasoning behind this. You can and do pick up training from other submissives. All the time, I am asked for help and assistance and can only hope that along with the advice they are learning how to figure it out for themselves and internalize it.
You may not actively want a mentor, but each and every submissive you exchange information and knowledge with is mentoring you and you are mentoring them. Even wise and experienced submissives learn from the younger. How do you see your conversations with submissives improving your own submission? If you can't see it, look harder. And if that doesn't help you, use this site as an example. You are reading this post, picking up information and many of you will take something away from it and learn. Others will find another article to do the same thing.
I'm just a submissive with an ability to express myself and a desire to help other submissives. I am a tool that a Dominant will want you to come seek out when you need to understand your submission and improve it. So the next time that you hear Slave Training and a Master that says they can train you, I'd ask direct questions as to how they can show you about surrender when they do not submit. It's not a challenge to Dominance at all for they can train you - just not in your own submission. You have to seek that out; whether within you or from senior submissives.
