Verily We sent messengers before thee, among them those of whom We have told thee, and some of whom We have not told thee;... (The Holy Qur'an, Al-Ghafir, 40:78)

"I will teach you, brethren, the Uncompounded and the way going to the Uncompounded. Now what, brethren, is the Uncompounded? The destruction of lust, of hatred, of delusion, brethren, is called the Uncompounded. And what, brethren, is the way going to the Uncompounded? It is mindfulness relating to the sphere of the body that is so called."
