“At the end of what is called the "sexual life" the only love which has lasted is the love which has everything, every disappointment, every failure and every betrayal, which has accepted even the sad fact that in the end there is no desire so deep as the simple desire for companionship.”

On Virginity, Chapter 18

Variant: Believe me, every heart has its secret sorrows, which the world knows not, and oftentimes we call a man cold, when he is only sad.
Context: "Ah! this beautiful world!" said Flemming, with a smile. "Indeed, I know not what to think of it. Sometimes it is all gladness and sunshine, and Heaven itself lies not far off. And then it changes suddenly; and is dark and sorrowful, and clouds shut out the sky. In the lives of the saddest of us, there are bright days like this, when we feel as if we could take the great world in our arms and kiss it. Then come the gloomy hours, when the fire will neither burn on our hearths nor in our hearts; and all without and within is dismal, cold, and dark. Believe me, every heart has its secret sorrows, which the world knows not, and oftentimes we call a man cold, when he is only sad."

The Ethics Of Aristotle (Vol. I)

Source: Gospel of Barnabas (c. 16th century AD manuscript), Ch. 33. The gospel's origins and author have been debated; several theories are speculative, and none has general acceptance. The Gospel of Barnabas is dated to the 13th to 15th centuries,[2] much too late to have been written by Barnabas (fl. 1st century CE). Many of its teachings are synchronous with those in the Quran and oppose the Bible, especially the New Testament; some, however, contradict the Quran.

The Spiritual Message of Hazrat Inayat Khan
Context: Is a Sufi a follower of Islam? The word Islam means 'peace'; this is the Arabic word. The Hebrew word is Salem (Jeru-salem). Peace and its attainment in all directions is the goal of the world.
But if the following of Islam is understood to mean the obligatory adherence to a certain rite; if being a Muslim means conforming to certain restrictions, how can the Sufi be placed in that category, seeing that the Sufi is beyond all limitations of this kind? So, far from not accepting the Quran, the Sufi recognizes scriptures which others disregard. But the Sufi does not follow any special book. The shining ones, such as 'Attar, Shams-i Tabriz, Rumi, Sadi, and Hafiz, have expressed their free thought with a complete liberty of language. To a Sufi, revelation is the inherent property of every soul. There is an unceasing flow of the divine stream, which has neither beginning nor end.

Our poor people are great people, a very lovable people, They don’t need our pity and sympathy. They need our understanding of love and they need our respect.
