By churning of the Athatvaveda, the guru-oriented (Kanad) in his Vaisesik recited about gunas, the qualities (of the matter).
He produced the theory of sowing and reaping(giving and taking) and told that at appropriate time only, one would attain the fruit.
Everything operates in His divine will, hukam(to which he calls apurva) and whosoever accepts the divine-will stablizes his self in equanimity.
The jiva must understand that nothing happens of its own (and our ownselves are responsible for our good or bad actions) and hence nobody as good or bad should be lodged in mind.
Rishi Kanad has said that as you sow, so shall you reap.
Listen to the injustice of the satyug that only because of a single evil-doer the whole world would suffer.
In the treta, the whole city suffered because of one evil-doer and in dvapar this suffering was limited to the one family and the family underwent the igominy.
But in the kaliyug only he suffers who commits evil deed.
