The three primeval qualities of nature are Sattva (mode of goodness), Rajah (mode of passion) and Tamah (mode of ignorance). All these three modes of qualities, produced by material nature, confine the immortal soul to the mortal body. Now, the mode of goodness being purest than others confines in the happiness. The mode of passion confines in the material fugitive activities and the mode of ignorance enveloping the wisdom is enamoured in misfortune.
From the material nature is created six enemies of life at every moment: sex-passions (kaam), rage (krodh), greed (lobh), infatuation (moho), vanity (mada) and envy (matsarya). Superabundance and the influence of these six passions sometimes outpoured the emotion of human life and were sometimes devastated. Human life, as influenced by these six passions, was cast off to the earth like dried leaves.
The reason for this short explanation is that the collection of six stories described how the human life is cast off like dried leaves, due to the influence of the six passions.
The readers will get concrete indication about the six enemies of human life, which may help them to adjust their lives in a righteous way.
