Every chapter was at least 90% about the author, her life and the lessons she's learned from her own personal, subjective experiences. From poverty Helen has evolved to a condition of opulence, commanding to-day an income aggregating tens of thousands of dollars annually. From a position of shrinking self-denial she has risen to a plane of powerful selfhood, and through its power has conquered all undesirable environments; not poverty alone, but disease. At a time of life counted by the world as old age, instead of getting ready to die she is preparing to live. Her life story, therefore, is a significant lesson to all who are struggling with unfavorable conditions, even were it told alone and with no attempt to disclose the laws which govern her success.

“Know yourself” is one of the great commandments. 
The more truly a man knows himself, the more he respects and reveres himself. The more he knows himself the more he know the law; the more he reveres himself the more he reveres the law; for the law and man are one; they are the internal and external of the one omnipresent life. And to understand this fully is to make the atonement – the at-one-ment – between the life principle and man, by which man’s life becomes identical with it, and he loses the very remembrance of sin, disease and poverty, and begins to step forth into wonderful comprehension and fellowship with the divine life – that of unbroken progression in constantly increasing phases of happiness and power.

And this is what Mental Science is doing for the world. It is a teaching man to know himself. In learning what he truly is, he cannot fail to learn that he has no fellowship with what we call “sin, sickness and poverty,” and these negative conditions – which are but ignorant denials of absolute truth – fall from him like old and worn-out garments.
