Jalaludin Rumi is acknowledged as the greatest of all the Muslim mystics, the Sufis, and their greatest poet. He speaks to people all over the world in their hearts, and calls them to the koan, to transcendence, and to repentance, in several forms, including music and dance.
Like other mystic and Sufi poets of Persian literature, Rumi's poetry speaks of love which infuses the world. Rumi's teachings also express the tenets summarized in the Quranic verse which Shams-e Tabrizi cited as the essence of prophetic guidance: "Know that ‘There is no god but He,’ and ask forgiveness for your sin" (Q. 47:19). In the interpretation attributed to Shams, the first part of the verse commands the humanity to seek knowledge of tawhid (oneness of God), while the second instructs them to negate their own existence. In Rumi's terms, tawhid is lived most fully through love, with the connection being made explicit in his verse that describes love as "that flame which, when it blazes up, burns away everything except the Everlasting Beloved."
Buddhists substitute knowledge of the Unborn, aka Buddha Nature, but fully agree on negating self, and on confessing delusions that result in evil thoughts, speech, and action. This does not mean destroying self, but recognizing that it never existed to become attached to. Nor does it mean wallowing in despair and hopelessness, as some Christians do over the doctrine of Original Sin.
Jews started with
Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy might.
Tanakh does not explain how to use this as a koan meditation, but doing so is fundamental in Hasidism.
