Hey, way to go Wants2fly. Teachers still pull that stuff? Hard to believe, especially for the subject matter. Good for you for accepting that about your self. If everybody was extroverted there would be no such thing as extroverted or introverted... the only reason that people are attracted to extroverts is the stigma that society places on typeA personalities and the like. There's no reason to be like that unless you're a salesman or a performer or something. the rest of us humble folk shouldn't be looked down upon for doing our own thing. Without introverts, things like the internet wouldn't exist! (Geek stereotype, a joke LOL. Sorry, my room mate makes part of the internet work, he'd laugh at that. Meant to indicate introverts are SMART!)

WHAT IS SUFISM?
It is much more than what I can explain to you. Living and worshipping through sometimes intense rituals, sometimes being segregated from their societies through their personal rituals or beliefs. Ever heard of a (whirling) Dervish? That is a sect of Sufism. Sufism was made famous in the Western world by extreme Sufism, public acts of ritual worship, some meant to punish the body and cleanse the spirit and mind for god through suffering. Ripleys believe it or not type of stuff witnessed by tourists that roused curiosity in Europe and America. Not all Sufis are so extreme. There is a focus on self-denial, imposing poverty and seclusion, to become closer to god, in the same way that many Catholic saints did. Sufis are known for being to Islam (at least the parts of Islam that recognize Sufism as Muslim, because some sects do not) as monks or nuns, or most extremely, as saints are to Catholics. To be Sufi is to be DEVOTED, mind spirit and body, to god, in the way that St. Francis was for example, giving all your life for god and god's intent for us as humans but not necessarily following a set of written rules. Some Sufis do not even necessarily follow the Qur'an, rather have their own ultimate truth that they live by, in accordance to what their heart tells them god would want. It is a way of life, moreso than religion it's self, as it is a very personal ongoing relationship with the creator that is lived every moment.

A small description of Sufism that I scammed off a website:
Sufism or tasawwuf, as it is called in Arabic, is generally understood by scholars and Sufis to be the inner, mystical, or psycho-spiritual dimension of Islam. Today, however, many Muslims and non-Muslims believe that Sufism is outside the sphere of Islam. Nevertheless, Seyyed Hossein Nasr, one of the foremost scholars of Islam, in his article The Interior Life in Islam contends that Sufism is simply the name for the inner or esoteric dimension of Islam.

After nearly 30 years of the study of Sufism, I would say that in spite of its many variations and voluminous expressions, the essence of Sufi practice is quite simple. It is that the Sufi surrenders to God, in love, over and over; which involves embracing with love at each moment the content of one's consciousness (one's perceptions, thoughts, and feelings, as well as one's sense of self) as gifts of God or, more precisely, as manifestations of God.

That is all.
