If you read simply Mahābhārata, which is meant for the śūdras and the woman class and the less-intelligent persons born in higher class society, you will find in Mahābhārata so sublime literature. You will find sociology, history, religion, culture—everything. But this was meant for the less-intelligent class. Now how much we have been degraded that we cannot understand even Mahābhārata. And in the Mahābhārata is the Bhagavad-gītā. Bhagavad-gītā is the portion of Mahābhārata. And such Bhagavad-gītā is being studied by many great scholars and philosophers at the present moment—still they cannot understand.
Try to understand: Which was made for the less-intelligent class of men, now it is very difficult to understand. So what class of men we are? That is my point. Strī-śūdra-dvijabandhūnāṁ. The Mahābhārata was meant for less-intelligent class of men and women, and now at the present moment we cannot even understand Mahābhārata. Then what less-intelligent class of men we are? Try to understand. Or what intelligent class of men were there. That is to be understood.
