Bhagavad-gita As It Is Lectures

The fullest revelation of knowledge in Satya-yuga there was automatically. People were so advanced. Just like gradually we are declining our memory, duration of age, so many facilities we have declined. So in Satya-yuga people were by nature fortunate to have many facilities. So for this age, when we are in very fallen condition, this facility is offered so that we can take the same advantage as people in the Satya-yuga had by other processes.
