Few people have asked me what is humility? I give an answer but for some reason I am never satisfied with my answers. Below is an answer Prabhupada gave to a devotee Harivilas das.
Humility means that you are convinced beyond any doubt that there is nothing in this world, absolutely nothing in this world, not your money, not your family, not your fame, not your gun, not your education, nothing that will save you except the mercy of Krishna. When you are convinced like this, then you are humble - words of Prabhupada as recalled by Harivilas das
Prabhupada, I gather, is basically saying any number of material security or plans to safeguard one's self is futile but to take shelter of Krishna is the only way. Real humility begins with acknowledging one's own helpless nature and at the same time acknowledging Krishna's supreme dominion and in that mood to take shelter of Krishna.
