From Chapter 5 of AiTL:
…words are the way we articulate mind, and the most profound spiritual experiences transcend the mindís boundaries. This gap leaves the mind groping for signs and signifiers with which to communicate meaning. Words are what our minds create in order to participate in the arena of circumstance; in contrast, profound spiritual experiences can take us to the source of this arena. So our language can leave us feeling like weíve been asked to repair a watch with a truck mechanicís tool set. Some rare individuals have a gift for being able to point practitioners verbally into the eye of Spirit. But, those who are best at it merely point us in the right direction. They are careful never to allow us to confuse their words with what their words are pointing out. This is part of what makes these teachers so great. Great teachers, in whatever their form, recognize that words often amplify our spiritual clumsiness, and so they stay silent, rightly believing that their presence and silent intention can communicate more generosity than their words. This silent presence is very difficult for egos to accept, which explains why most spiritual seeking can be so short-lived. Egos are not interested in anything revolutionary unless they can control the experience. When we learn to communicate in a way that isnít bound by egoís selfishness, our ego is forced to get out of the way of a white hot clarity of intentional generosity. Exposure to this flame of magnanimity has the potential to change egoís relationship to everything, since everything starts to reveal itself as an expression of exactly what is beyond the scope of anything ego can grasp. This kind of communication may or may not involve words or sound. But for those ready to communicate from and as Spirit, a deep, silent connectivity awaits them.
