Krsna says, sarva-dharman parityajya mam ekam saranam vraja [Bg. 18.66], but we are revolting, "Why? Why shall I surrender to You? This is too much You are demanding." This is going on. This is the disease. And to cure the disease Krsna Himself comes. Yada yada hi dharmasya glanir bhavati, tadatmanam srjami [Bg. 4.7]. But we are so stubborn that we won't, do not like to be cured.
So what Krsna will do? How Krsna will help? He is coming. He is sending His devotee. He is leaving behind Him the sastras.

[But the materialist] thinks that "What is the use of this slave mentality? This bhakti-marga is slave mentality. Instead of becoming God, they want to become servant or slave of God." No, this is not slave mentality. This is actual liberation, because our constitutional position is to remain. We are servant of Krsna. But somehow or other, we revolted. Still we are revolting.
Although Krsna coming and canvassing, "Just surrender unto Me," but still we are revolting. This is our disease.
