I think the whole point rests on the idea of self-discipline. The mind (thoughts) and emotions are tools which we use e.g. for self-expression, to engage in perception, among other processes in consciousness. If we don't control our thoughts and emotions, we become like workmen (humans) whose work (lives) are determined by the tools (thoughts and emotions), which is not respectable at all. But if we learn to control them, then we stand a chance at overcoming the chaos in our lives.

Unfortunately, these teachings also rest on the idea of 'self' being fundamental to everything and for those who are not inclined towards such a school of thought, it all seems like hogwash.

How does one cease the identification with thought if what the author speaks is true? — Posty McPostface

So far I only know of meditation.

One can approach the matter of "identification" from a number of ways. I am fond of the following from Zhuangzi:

" Kai-shi then replied, "I have heard my master say that they who skillfully nourish their life are like shepherds who whip up the sheep they see lagging behind." "What did he mean?" asked the duke. The reply was, "In Lu, there was a Shan Bao, who lived among the rocks, and drank only water. He would not share with the people in their toils and the benefits springing from them, and although he was now in his seventieth year, he had still the complexion of a child. Unfortunately, he encountered a hungry tiger, which killed and ate him. There was also a Zhang Yi, who hung up a screen at his lofty door, and to whom all the people hurried (to pay their respects). In his fortieth year he fell ill of a fever and died. (Of these two men), Bao nourished his inner man, and a tiger ate his outer, while Yi nourished his outer man, and disease attacked his inner. Both of them neglected whipping up their lagging sheep."
