“Critical thinking is deeper, the understanding the world is easier.”

Address to the European Parliament (2015)
Context: I am outraged and grieved by the recent attacks in some countries against Christian and minority communities. This is an offense against humanity as well as Islam. Arab Christians are an integral part of our region’s past, present and future.
Jordan is a Muslim country, with a deeply-rooted Christian community. Together, the Jordanian people make up an in- divisible society, friends and partners in building our country.
The world’s Muslims have a critical role in global understanding. Our faith, like yours, commands mercy, peace and tolerance. It upholds, as yours does, the equal human dignity of every person — men and women, neighbours and strangers. Those outlaws of Islam who deny these truths are vastly outnumbered by the ocean of believers — 1.6 billion Muslims worldwide. In fact, these terrorists have made the world’s Muslims their greatest target. We will not allow them to hijack our faith.

Card XXI : The World
The Symbolism of the Tarot (1913)
Context: The vision disappeared as suddenly as it appeared. A weird silence fell on me. "What does it mean?" I asked in wonder.
"It is the image of the world," the voice said, "but it can be understood only after the Temple has been entered. This is a vision of the world in the circle of Time, amidst the four principles. But thou seest differently because thou seest the world outside thyself. Learn to see it in thyself and thou wilt understand the infinite essence, hidden in all illusory forms. Understand that the world which thou knowest is only one of the aspects of the infinite world, and things and phenomena are merely hierolgyphics of deeper ideas."
