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. Once you see your mind, why pay attention to doctrines?

Worship means reverence and humility. It means revering your real self and humbling delusions. If you can wipe out evil desires and harbor good thoughts, even if nothing shows, it's worship. Such form is its real form.
The true Way is sublime. It can't be expressed in language. Of what use are scriptures? But someone who sees his own nature finds the Way, even if he can't read a word.
