Plato in his magnum opus Republic has given an Allegory of the Cave which is widely called Cave Theory to emphasise on the lack of education on our nature which is similar to the prisoners inside the cave .Prisoners inside the cave see only images of reflection which are only shadows of the reality in the dim light.Plato being the disciple of Socrates has written this as a dialogue between his brother and Socrates. The prisoners free themselves from the bonded chains in the caves and come out and see that what they have experienced is not reality but reality outside the cave exists. This allegory shows that the human senses when chained to the cave do not allow humans to think beyond the cave images. In this allegory Plato keeps mathematics, geometry and deductive logic at the third and highest level of education.
There is a similarity of this to Indian philosophy of Advaita, in which in simple terms it is said that what we experience is not the reality and it is more like an illusion what we dream in our sleep. Adi sankara when explaining this illusory phenomenon says that this happens due to Avidya or lack of education which is awareness. When we realise our true self we become one with our Creator and realise there is only one Absolute and there is no second- "A dvaita"- only" Brahmam Sathya" and this "Jagat(Earth) Mythya(myth/illusion)".
So in a way both the concepts of philosophy talk about Education or lack of it and its effect, impact on human understanding. Human minds are conditioned by experiences, perceptions and memory impressions and their interplay, without comprehension of the reality or the true nature of human existence.
Bhagawan Krishna in his Gita also emphasizes on this Avidya (Chapter 4)and suggests ways to come out of it(chapter 5). The best and the easiest way is to surrender our ego to Bhagwan and continue with our duty selflessly without any attachment to the fruits of our actions.
