Answer: A person cannot control his thoughts. He cannot control himself in any way. Am I my own boss? Where do we see such things?! There is no such thing! But I have to invoke a positive force around me on such a level that it will influence me and sustain me. Then I will be able to control myself.
We always stabilize our state by external forces, by the environment, society, and external support, while a person has no control over it. He doesn’t know which state he will be in the next moment, so how can he control anything?
A person can secure his future only if he prepares all the external vessels, desires. If I worry that the others have a secure future, I thus ensure my own future.
If a person is an element in a system, then how can he ask about what will happen to him? He depends on the whole system, especially since it is arranged so that he has the free will to strengthen his surrounding system and then he can ensure his future. He will never have more than he has prepared in the system, but if he hasn’t prepared it enough, he will receive blows so that he will discover the need to prepare it.
