Thale is creating his own path of cultivation. Since he does not have a master, he is coming up with ideas, testing them on himself, and creating a unique path.
That can be both a strength and a weakness, as it allows Thale to tailor his cultivation to his own needs and goals, but it also means that he may not have access to the guidance and experience of a master who has walked the path before him. It will be important for Thale to be diligent in his practice and carefully consider the consequences of his decisions in order to maximize the benefits of his self-directed cultivation. It may also be helpful for him to seek out resources and knowledge from other sources, such as books or other cultivators, in order to ensure that he is making informed decisions about his cultivation.
