I don't believe that the sort of experience that you describe is "the very opposite" of "organized religion" -- mystical, meditative, and/or monastic practices in a number of faith traditions (such as Hinduism, Buddhism, Judaism, Christianity, Islam, and so on) promote attainment of such experiences. If you find such experiences valuable, and if you approach various mystic, mediative, and/or monastic orders with an open mind, you may even find what looks (to outsiders) like senseless dogmas and rituals are actually time-tested ways to discipline bodies and minds in such a way that you would be able to achieve an experience "beyond labels, language, images, anticipations, attachments" as you put it.
For a majority of the religious (whether or not they favor the kind of "religious experience" that appeals to you, whether they are politically on the right, the left, or the center) today, what they find most valuable in religion is precisely the fact that it's organized, i.e., voluntarily organized by communities of people who seek to share more or less the same belief system (even as they argue about it and change it -- sometimes only a little, other times drastically), confront social problems together in light of its ethical ideals and principles, and care for one another in the spirit of mutual aid. For a majority of the irreligious today, too, religion that matters in society (especially to the point of affecting their relation to the religious), for better or worse, is such enduring collective practices rather than fleeting private experiences of transcendence of "labels, language, images, anticipations, attachments" (which do not affect others one way or another). -- Yoshie
