God = Love + Our Efforts & We The People Can Make This World Into Heaven

http://en.wikipedia.org/wiki/Rumi

Why should I seek? I am the same as
He. His essence speaks through me.
I have been looking for myself!

Listen to the reed and the tale it tells,
How it sings of separation...

Hussam implored Rumi to write more. Rumi spent the next twelve years of his life in Anatolia dictating the six volumes of this masterwork, the Masnavi, to Hussam.

In December 1273, Rumi fell ill; he predicted his own death and composed the well-known ghazal, which begins with the verse:

How doest thou know what sort of king I have within me as companion?
Do not cast thy glance upon my golden face, for I have iron legs.

Rumi died on 17 December 1273 in Konya; his body was interred beside that of his father, and a splendid shrine, the Yeşil Türbe (Green Tomb, قبه الخضراء; today the Mevlana Museum), was erected over his place of burial. His epitaph reads:

When we are dead, seek not our tomb in the earth, but find it in the hearts of men.

A page of a copy circa 1503 of the Diwan-e Shams-e Tabriz-i.The general theme of Rumi's thought, like that of other mystic and Sufi poets of Persian literature, is essentially that of the concept of tawhīd – union with his beloved (the primal root) from which/whom he has been cut off and become aloof – and his longing and desire to restore it.

The Masnavi weaves fables, scenes from everyday life, Qur’anic revelations and exegesis, and metaphysics into a vast and intricate tapestry. Rumi is considered an example of Insan-e Kamil — Perfect Man, the perfected or completed human being. In the East, it is said of him that he was "not a prophet — but surely, he has brought a scripture".

Rumi believed passionately in the use of music, poetry, and dance as a path for reaching God. For Rumi, music helped devotees to focus their whole being on the divine, and to do this so intensely that the soul was both destroyed and resurrected. It was from these ideas that the practice of "whirling" dervishes developed into a ritual form. His teachings became the base for the order of the Mevlevi which his son Sultan Walad organized. Rumi encouraged samāʿ, listening to music and turning or doing the sacred dance. In the Mevlevi tradition, samāʿ represents a mystical journey of spiritual ascent through mind and love to the Perfect One. In this journey, the seeker symbolically turns towards the truth, grows through love, abandons the ego, finds the truth, and arrives at the Perfect. The seeker then returns from this spiritual journey, with greater maturity, to love and to be of service to the whole of creation without discrimination with regard to beliefs, races, classes, and nations.

According to Shahram Shiva, one reason for Rumi's popularity is that

Rumi is able to verbalize the highly personal and often confusing world of personal/spiritual growth and mysticism in a very forward and direct fashion. He does not offend anyone, and he includes everyone. The world of Rumi is neither exclusively the world of a Sufi, nor the world of a Hindu, nor a Jew, nor a Christian; it is the highest state of a human being — a fully evolved human. A complete human is not bound by cultural limitations; he touches every one of us. Today, Rumi's poems can be heard in churches, synagogues, Zen monasteries, as well as in the downtown New York art/performance/music scene.

According to Professor Majid M. Naini, Rumi's life and transformation provide true testimony and proof that people of all religions and backgrounds can live together in peace and harmony. Rumi’s visions, words, and life teach us how to reach inner peace and happiness so we can finally stop the continual stream of hostility and hatred and achieve true, global peace and harmony.

In other verses in the Masnavi, Rumi describes in detail the universal message of love:

Lover's nationality is separate from all other religions,
The lover's religion and nationality is the Beloved (God).

The lover’s cause is separate from all other causes
Love is the astrolabe of God's mysteries.
