It seems there is a natural evolution from the depths of ignorance towards knowing. This is often called Ripening. I do not really know why it happens, but I can sense it faintly. It also seems that the human experience is an important milestone on this path of evolution, at least that’s what is seen in this world. From time to time some humans realize their true nature and emerge out of this deep ocean of ignorance like a bubble. This happens irrespective of place, race, gender or time. It also appears that this process is speeding up, but it can be an illusion because human population is growing rapidly, there are more people and so more wise people. Some people out of these few come out in open and try to tell others what they have realized. We call such a person a teacher or a Guru.
The literal meaning of the word Guru is "remover of darkness", it also means great, mighty or giant. The former meaning is implied when its about teaching. Darkness implies ignorance. Note that it is not "bringer of light" or something like that because as we know, the light is always there. It is occluded by ignorance. So such a person does nothing but shows that you are in a dark pit and often suggests a way out. A teacher does not and cannot pull an ignorant out of the pit, he merely hints at it, maybe gives a helping hand. The student pulls himself out. The teacher acts as a trigger.
