Srimad Bhagavatam 6.4.31 describes how the Lord inspires material arguments within the hearts of those who wish to engage in them. Therefore, such persons continue to argue about material forms, illusions, and mistakes and never reach any conclusion. Since these topics cannot be resolved, people who argue them become progressively disappointed and their minds remain disturbed, their hearts hard. It is not possible for such persons to solve their arguments because there are no solutions in the material world. The only solution to material life is Krishna consciousness. Those who take to Krishna consciousness find their tough hearts softening. That is because they have accepted the conclusion presented by the mahajanas.
