You say that 1 in every 50 succeed in completing the training process, why is the percentage is so low?

Most people ignore their dark side when doing the tutorials and fall into the trap of resisting the resetting of their minds. They are tricked into clinging to old fruitless concepts, rather than making the required effort even although absolutely nothing is asked of them on my part. Humans are naturally designed to choose darkness over light: this is explained in the tutorials.

Does it required certain talent or given ability to complete the training?

No special skills or talent are required, but you do have to be smart enough to see the value in following the instructions in the tutorials, rather than trying to change the new knowledge back to match old mindsets

What have you benefited for giving away this course for free?

It was not my idea to offer this knowledge for free; I was instructed to do so by The Father. I have since been made aware of the great value in that strategy: (a) To teach others is to learn from their mistakes rather than having to live through them personally. (b) When I saw that there are religious fanatics in this world who are willing to slaughter thousands of people because they are unknowingly being guided by the dark side of humanity, which disguises itself as god. Then the value of opening up the truth about what the word god really means - for all people to know freely, really struck home to me. ( c) Offering this knowledge for free was too great a concept for me to come up with, but I am being rewarded. My spiritual parents are now training me in how to predict things like lottery numbers, stock movements etc. I pay the bills for now, but I will benefit financially, my training in the lottery area is nearing completion.

I’ve done all that and I know how to meditate, just need to know how to learn how to move objects with my mind without ordering any books or anything.

Solo spiritual development is serious business; you cannot just send information out. Lapse training is quite unwise; it is the equivalent of arming a child with a loaded gun. All tutorials must be answered 100% accurately before moving on to the next stage.
There is no meditation involved in Solo Spiritual Development and what ever you learnt before cannot support accessing this level of power.

What do I need to do?

This is not a suggestion on my part - it is just the answering of your question. Accessing Thought power can take years. It took me over fourteen years of training to learn it. You will have to set your mind to a lifetime commitment, and you will not be able to hold on to any meditation or other processes you have already learnt.

What can be done with an increase in mind power before I start the tutorial?

Your question is like asking me what can be done with an increase in pay. You will have to answer that question for yourself.
