Without this understanding , no teaching can lead to an efficient result , and teaching that does not awaken in those who received it a personal resonance can not provide any kind of knowledge. This is why Plato said that ” everything that man learns is already in him.” All experiences , all the external things around are indeed an opportunity to help him realize what is in himself . this awakening is what Plato calls anamnesis , which means ” remembrance “.
If this is true for all knowledge, this is even more for a higher and deep knowledge, and when the man advance to this knowledge, all exterior and sensitive resources become increasingly inadequate, until ‘ they finally lose all utility . If they can help to get close to the wisdom to some degree , they are powerless to actually acquire it and it is commonly said in India that the real guru or master is in man himself and not in the outside world , although an exterior help may be useful in the beginning to prepare man to find in himself and by himself what he can not find elsewhere, and particularly what is above the level of rational knowledge . In order to achieve this knowledge ,it s necessary to realize some states which get more deep towards the center , which is symbolized by the heart , where the consciousness of man must be transferred to make him able to reach the real knowledge.
