II श्रीराम जय राम जय जय राम II

कबीर ते नर अंध हैं, गुरू को कहते और I
हरि के रूठे ठौर है, गुरू रूठे नहिं ठौर II

A blind man knows he cannot see, and is glad to be led, though it be by a dog; but he that is blind in his understanding, which is the worst blindness of all, believes he sees as the best, and scorns a guide. Willful ignorance can lead to hate and prejudice. Because they know what they're doing is wrong and illogical, but decide to do so anyway. 
Plain ignorance can be chalked up to not knowing any better, but willful ignorance is much worse.

"Kabir says, those who are blinded by ignorance go blatantly onwards declaring they need not listen nor learn, for they never understand the importance of Guru in their life. The road to God Realisation is like climbing a high mountain. People often do not anticipate a number of things about the path to God. The Guru is like a mountain guide who knows the terrain and helps us along until we have reached the peak. It would be foolish to try and climb this high mountain without a guide. We can never make it to the top on our own."
