In plain words
A pure mind is the road to goodness; a pure mind is a mighty power; to have a pure mind is the chief thing of all: do not forget this good word.

The great means for the blossoming of human life is self-confidence itself. Today, because this self-confidence is lost, life travels a road of confusion. When a human being is born, he has no vices at all; he is without any such quality. But as time passes, as food changes, as likings grow, the life of man strays somewhat from the road. The company he keeps gives man room to develop … vices. These very vices have today been taking shape in man merely as a craving, as a taste. Right then, likes and dislikes take root in man. Next, as soon as schooling begins, along with it the vices called attraction, pride, Ahaṅkāra and possessiveness spread through the body from foot to head and dance a wild dance. Forgetting that the distinction of education is Viveka, he thinks of himself alone as great and believes that no one is greater than he.
… the young keep running after friendship of some kind. Crazed with the intoxication of youth, they look upon others as lower than a blade of grass. If man would live as man, if a human being would live as a human being, he must face immense hardships, losses and misfortunes. And so: only the man who withstands the setbacks and the shocks that life brings and pushes on forward through them can be recognised as a true man. But man today gives in to such hardships and losses, to reproaches and harsh words, becomes a slave to the senses, gives room only to pomp and pride, and wastes his life. Man today yields to a petty, restless mind and to the objects of the senses. The thirst of man today is marriage. Enslaved to such a thirst, he forgets his humanness. But if man today asks himself the question "Am I a human being?", the right answer is found in no man.
