Ignorance of others when practising the teachings of the Buddha Ignorance is described as not knowing about dukkha. If one knows dukkha and understands the cause of dukkha is starts with ignorance, how does one traverse ignorance of others?

For example, the Buddha one would imagine would have had to experience the ignorance of others. Would he have ignored it? Would he have attempted to enlighten them? Would he have empathized with them?
Ignorance is a personal thing, and Buddhism speaks of a specific kind of personal ignorance -- that of dukkha.

The ignorance of others is irrelevant. Yes, one tries to help others, but transcending ignorance is a matter of transcending ONE'S OWN IGNORANCE and implies nothing about the ignorance of others.  However, one might be in a better position to be patient and hence work with others.
