There is in the "New Age" movement something of a backlash, if you will, against western culture, including western religion. There is an emphasis on individual spirituality as opposed to communal or institutional spirituality. Only oriental spirituality works this way, or so the prevailing thought goes.
Nothing could be further from the truth, however. Throughout the Middle Ages, mysticism maintained a continuous tradition within the Church, and in fact, many mystical ideas have been incorporated into Catholic, Orthodox, and Protestant teachings.
When Islam arose, late in the first millennium, a mystical element appeared within it, known as Sufism. Likewise, Judaism has developed its own long mystical tradition.
Christianity was, almost from the very beginning, a mystery religion, as well, with many mystical ideas at its core. Renowned Christian thinkers such as St. Paul, St. Augustine, St. Jerome, St. Benedict, Bernard of Clairveaux, were all mystics, who inspired & directed later Christian thought. The mendicant movement (i.e. the friars) were inspired by the mysticism of St. Francis of Assisi and St. Dominic (hence, the twin mendicant orders, the Franciscans & the Dominicans). All of the great scholastics & intellectuals of the Middle Ages — men such as Grosseteste, Roger Bacon, Peter Abelard, and so on — were mystics at heart; their intellectual pursuits resulted directly from their mystical beliefs.
The pursuit of metaphysics ultimately led to the "scientific method," a means by which to verify and refine metaphysical concepts (much as logic & rhetoric are tools for understanding). In turn this led to the foundation of modern science. Even well into the Renaissance, people we consider to be early scientists (Isaac Newton, Galileo, etc.) were essentially mystics, hoping that their studies of the physical world would reveal divinity to them. They believed that God had established the laws of nature — therefore, if you understand them, you get that much closer to God.
In a very real way, we owe all of our amazing technology — including computers and the Internet, by way of which you're reading this document — to medieval mystics. In their drive to understand God more intimately, they also learned a good deal about the physical world, and we now enjoy the fruits of that labor. Occidental (western) mysticism is, indeed, alive & well, in spite of the fact that many people believe that mysticism is an oriental phenomenon.
