~Seyyed Hossein Nasr
"O thou soul which are at peace, return unto thy Lord, with gladness that is thine in Him and His in thee. Enter thou among My slaves. Enter thou My Paradise."
(Quran - LXXXIX; 27-30 (trans. by M. Lings.)
The function of religion is to bestow order upon human life and to establish an "outward" harmony upon whose basis man can return inwardly to his Origin by means of the journey toward the "interior" direction. This universal function is especially true of Islam, this last religion of humanity, which is at once a Divine injunction to establish order in human society and within the human soul and at the same time to make possible the interior life, to prepare the soul to return unto its Lord and enter the Paradise which is none other than the Divine Beatitude. God is at once the First (al-awwal) and the Last (al-akhir), the Outward (al-zahir) and the Inward (al-batin). By function of His outwardness He creates a world of separation and otherness and through His inwardness He brings men back to their Origin. Religion is the means whereby this journey is made possible, and it recapitulates in its structure the creation itself which issues from God and returns unto Him. Religion consists of a dimension which is outward and another which, upon the basis of this outwardness, leads to the inward. These dimensions of the islamic revelation are called the Shariah (the Sacred Law), the Tariqah (the Path) and the Haqiqah (the Truth), or from another point of view they correspond to islam, iman, and ihsan, or "surrender", "faith" and "virtue".
Although the whole of the Quranic revelation is called "islam", from the perspective in question here it can be said that not all those who follow the tradition on the level of islam are mu'mins, namely those who possess iman, nor do all those who are mu'mins possess ihsan, which is at once virtue and beauty and by function of which man is able to penetrate into the inner meaning of religion. The Islamic revelation is meant for all human beings destined to follow this tradition. But not all men are meant to follow the interior path. It is enough for a man to have lived according to the Shariah and in surrender (islam) to the Divine Will to die in grace and to enter into Paradise. But there are those who yearn for the Divine here and now and whose love for God and propensity for the contemplation of the Divine Realities (al-haqaiq) compel them to seek the path of inwardness. The revelation also provides a path for such men, for men who through their iman and ihsan "return unto their Lord with gladness" while still walking upon the earth.
While the concrete embodiment of the Divine Will, which is the Shariah, is called the exoteric dimension in the sense of governing all of man's outward life as well as his body and psyche, the spiritual path, which leads beyond the usual understanding of the "soul" as a separated and forgetful substance in the state which Christians call the "fallen state", is called the esoteric dimension. In Sunni Islam, this dimension is almost completely identified with Sufism (tasawwuf) while in Shi'ism, in addition to Sufism, the esoteric and the exoteric are intermingled within the general structure of the religious doctrines and practices themselves. And even within Sunnism, there is an intermediate region between the exoteric and the esoteric, a world of religious practice and doctrines which while not strictly speaking esoteric are like the reflection of the inner teachings of Sufism within the whole community and a foretaste of its riches. In fact, many of the prayer manuals which occupy such a position in the Sunni world, such as the Dalail al- khayrat, were written by Sufi masters, while in the Shi'ite world, the prayers almost all of which, such as the al-Sahifah al-sajjadiyyah of the fourth Imam Zayn al- Abidin, were written by esoteric authors, partake of both an esoteric and an exoteric character. Occasionally, there has even been the penetration of one domain upon another, such as the sayings of many of the Imams which have appeared in Sufi writings and even of some Sufi writings which have penetrated into certain Shi'ite prayers identified with some of the Imams.
Prayers such as those of Khwajah 'Abdallah Ansari, the great saint of Herat contained in his Supplications (Munajat) are at once the deepest yearning of the heart for the Ineffable and the Infinite and common devotional prayers chanted by many of the devout in the community and thus belonging to the intermediate level alluded to above:
I live only to do Thy will,
My lips move only in praise of Thee
O Lord, whoever becometh aware of Thee
Casteth out all else other than Thee.
O Lord, give me a heart
That I may pour it out in Thanksgiving
Give me life
That I may spend it
In working for the salvation of the world.
O Lord, give me understanding
That I stray not from the path
Give me light
To avoid pitfalls.
O Lord, give me eyes
Which see nothing but Thy glory.
Give me a mind
That finds delight in Thy service.
Give me a soul
Drunk in the wine of Thy wisdom.
