BG Chap 14 - Immediate effects of the modes

From sattva is born knowledge characterized by revelation or truth. This leads to happiness. From rajas comes greed, a particular craving, which cannot be satisfied by indulgence in sense objects. This leads to a little happiness and plenty of grief. From tamas arise inattention, illusion and ignorance, which all lead to sorrow with total unconsciousness. When the mode of goodness is developed, people will see things as they are. In the mode of ignorance, people are just like animals and cannot see things clearly. In the mode of passion, people become greedy, and their hankering for sense enjoyment has no limit. Thus the immediate effects give rise to the results of actions discussed previously.
