''"For a thousand years, we have kept this knowledge. The eyes of the unfavored son may look upon it, and learn the secrets of his power. When he has set his feet upon the cursed path, he may look yet deeper. Only the eyes of his father may see all and know all. The sharingan is awakened for the first time when a son of the Uchiha looks upon a god of death, and sees his face reflected in its eyes. But it is only mastered when he becomes that god, and one whom he dearly loves looks into his eyes, and sees their death there. In the left eye, a weapon to obliterate the minds of all your enemies. In the right, a weapon to obliterate their bodies. From both springs the shield about that no weapon may pierce. It is power born of pain, and pain will be the price paid for its use. Like the grief from which it came, it will devour the sunlight of your world, until all that is left to you is darkness. This is the Mangekyo Sharingan. I was not the first and I will not be the last."''

--- Uchiha Izuna, Year 897 of the Age of the Rikudo Sennin.

There is nothing sacred about those techniques Sig. The Uchiha have a legacy of fratricide and betrayal. Where the Senju died saving their loved ones, the Uchiha died murdering them for power. The above is a quote I have sampled from a fanfiction. It is probably the best and the only depiction of what may have been written in the Naka Shrine.
