Hakim Sanai, the 12th c. mystical poet from Afghanistan, wrote an enormous quantity of verse, including his master work, “The Walled Garden of Truth,” which inspired Jelaluddin Rumi, and has served as a Sufi text book for 900 years. Nevertheless, Shams-i Tabrizi, in his “Discourses”, reported:

At the time of death, Sanai was saying something under his tongue. When they put their ears next to his mouth, they heard:
“I’ve turned away from all I’ve said —
There’s no meaning in speech, no speech in meaning.”
