Once attached, you're unaware. But once you see your own nature, the entire Canon becomes so much prose. It's thousands of sutras and shastras only amount to a clear mind. Understanding comes in midsentence. The ultimate Truth is beyond words.
Doctrines are words.
They're not the Way. The Way is wordless. If you see your nature, you don't need to read sutras or invoke buddhas. Erudition and knowledge are not only useless but also cloud your awareness. Doctrines are only for pointing to the mind.
