Humility is all about being truthful and honest.
The more we are happy in Krishna Consciousness, the more we become purified.
Out of all the opulences of a living entity its humility which pleases Krishna. Other opulences can also please Krishna if offered with humility.
Krishna exalts those who are humble and humbles those who exalt themselves.
The more serious you are about spiritual life, the more you keep your mind in captivity.
That is truth. In that truth, there is real happiness. And there is nothing that could disturb that happiness.
