Kmicic, let me set a different context a bit that might be more useful. Instead of talking about shortcuts, let's talk about the foundations.
So instead of talking about Knowledge Shortcut, let's say Fundamental Knowledge.
When it comes to working on the self, the most important ideas seem to be the idea of Free Will and Service To Others.
Cassiopaeans, when asked about one of the most important principles that govern our lives, respond that it is the law of Free Will. The fragment below is confirming:
(...)Some fundamental law of creation?
A: Free will.
Of course, our will is limited, we live in bodies, we live in material reality, there are 4 Density STS beings that influence our reality at global level, and we are too small to do anything about it, however, we are left to decide what happens in ourselves and in our immediate surroundings.
The next thing is Service To Others. Cassiopaeans talk many times about the division into Service To Others and Service To Self, so I will not mention any specific fragments, because it would be too much, but I will try to outline the general concept.
In the Service To Others, the individual tends to dissipate energy, he/she adds this energy to the ocean of life so that others can also grow and develop. In Service to Self, energy is blocked and captured by the individual.
It seems that spiritual growth for us here on Earth is to utilize these two conceptions of Service to Others and Free Will in our daily relationships with other people. But what is it about and how to use it in everyday life?
Let's make two examples, the easiest way to talk is based on examples...
We have two friends who decide how to spend time together. Suppose things happen in two alternate realities. In one [ 1) ], this pair of friends choose the STS path, and where Free Will is also broken. And in the second [ 2) ] reality, friends choose STO and Free Will.
1) It's Saturday, a day off, one of two friends decides to spend his free time. He comes up with an idea to meet up while watching comedy series. He buys good food and drink. He wonders who to invite. He invites the person in whom he subconsciously recognizes someone who, like him, will accept this way of spending time and a similar view of reality.
Then they meet, laugh and talk together, feel the pleasure that comes from laughing. It's good, their bellies are full and they enjoy drinking sweet drinks. Entertainment is easy and fun, the series do not require effort from them, you just need to look at the screen.
At some point, the episode of the series ends and the guest proposes to play something else now, some other movie that he would like to watch, but the host does not want it, attacks the guest, of course not directly, but begins to undermine the level of the guest's taste, the quality of the film that the guest wants watch, looking for ways to get him to choose the movie he wants, crushing the individuality and sympathies that his guest has, leaving him feeling humiliated and choosing the movie he wants to watch.
What can we say about this situation? The host is focused on his pleasure, he chooses what gives him comfort and joy. He surrounds himself with a person he thinks will be better for his personal purposes. There is no interest in objective reality here, no effort to understand the film, no form of conscious suffering. It even breaks the visitor's free will by imposing his choice of the film on him, trampling his own view and will.
I think this attitude reflects the 3 Density STS way of being, plus Free Will is broken which leads to Karma. Karma will manifest itself in such a way that at some point in his life the host will be a guest in someone's home (or something similar will happen) and placed in a situation that he once created.
2) Second example. In that different reality, where the person has a choice of how to spend the Saturday, he wants to do it differently. He decides to watch a documentary on a topic he does not know, but which could potentially bring the person closer to understanding objective reality. He states that it would be nice to invite one of his colleagues to also give him the opportunity to learn new knowledge from the movie watched, of course after accepting the invitation.
Besides, he may not be his best friend, but he knows that this person has interesting ideas and it would be fun to give himself a chance to get to know him better. After watching the movie together, they started arguing. In the first few minutes it turned out that they had a lot in common, but it soon became apparent that they disagreed on several important points. After trying to translate and persuade each other, they weren't too pleased with the other side's lack of understanding, but held back their reactions. Neither of them attacked the other. They decided to split up and the guest went home.
For some time after the meeting, the host thought to himself that he had invited such a guest for the last time and that he should have invited his best friend, it would not be so. But at some point he doubted his own narrative, he stopped being offended at his friend and returned his thoughts to what they were talking about and at some point he was surprised, he already knows what his friend was about. Suddenly the phone rang and it turned out that it was the same friend he was seeing, who told him that he was right, because he had checked something in the book, calmly, after returning home.
In the second example, the situation is different. The goal is to learn something about reality from a documentary. Friends do not focus on the well-being of eating, drinking and "good humor", but on discussions where they share their knowledge and, despite a lack of mutual understanding, inhibit their reactions that could hurt their interlocutor. There is a clear difference between the first and second ways of spending time.
The first is to focus on subjective perception of reality and well-being. Free Will is also broken by imposing one's own (STS and Karma). The second example is focusing on objective reality and sharing information. Understanding a documentary takes focus and is not easy. Negative reactions towards the other person resulting from a lack of mutual understanding are prevented, leading to friction and bypassing the behavior that could break the other person's Free Will and gain Karma.
In conclusion, I think there are no shortcuts to anything, neither in knowledge, nor in development, but we can talk about some foundations. Fundamental Knowledge.
These foundations seem to be the distinction between STS and STO, seeing Free Will in self and others, and when that Free Will is breaking. STO and STS, Free Will and Karma, these are all ideas that Cassiopaeans say are objective and govern the objective reality in which we exist, these are the foundations on which this universe stands and which permeate all existence in various forms.
And I think that on a practical, human level, this is exactly the kind of discernment, just like on the basis of these examples. I think the art is to choose behaviors that resemble those we see in example "2)" and avoid those in example "1)".
