Sorry for the late reply, but I have been busy planning and taking care of a trip to Japan, starting at the end of this month, and going til August

weee!
But I will sort of reply to the two above posts:
LW: I am glad my post makes sense on an intellectual level. Because I think it is important to combine the spiritual side with the intellectual. So that one gets a sort of spiritual intellect. I think this is important, to always keep ones mind sharp, and still develop ones spirituality. And also be able to express it to others, and live a religious/spiritual ethic life. (I think Ibn ‘Arabi has a lot of good reflections on this. I think it is from him I have gotten inspired to this idea. But I don’t see other traditions disagreeing with this point…)
Jikuhchagi: “Regardless, this is a world of duality so saying 'Words can be a necessary evil' is no worse (or misguided) than saying that 'Words can point to beautry'. Neither negates the other as they are two sides to the same coin”
That sentence shows we don’t disagree so much at all. I just have a bit of a different way of viewing it.
I view it, also as you say. There are two levels of reality. One is the conventional level, which is the level of distinction. Where paintings, words, music, selves are arising and dissolving etc. And then there is the Absolute level, which is the level where there is no distinctions. These two levels co-exist, and one cannot be without the other.
Now, from the conventional level, every talk about the Absolute is from a point of the conventional level. And will, as you also say, not ever convey the Absolute in its totality, but, as Nagarjuna also said, one cannot help but try to convey it anyway. So therefore the question arises: How does one use words the best as a skillfull mean to lead towards the moon

. And the same with music, paintings, and other arts and craftmanships.
I think this question is a necessary question to ask as an ethical question, since it will be the means of using the conventional as a skillfull means to lead others to realise certain aspects of reality. To use words wrongly, false words, will trap people further into a sort of lie that clings to the ephemeral phaenomenons in the conventional level.
Kûkai also explains (udfolder in danish, don't know a good word for it in english) out a theory of the correct way of using words a whole lot in his esoteric Shingon (which means “Truth Words” in Japanese.), where mandala, mantra, mudra etc. practises are used to attain enlightenment.
And to use words in a good way, I also think, as I replied to LW, that it is good to have sharpened ones spiritual intellect, and not just forget about that part of reality.
For, to be sure, to cling to the absolute, and forget about the conventional reality, is often referred to as Sunyata-sickness, or sunyata-perversity. Which is an attachment to the Absolute, where one will loose the ground for enlightenment, which is the conventional. The two levels co-exist.
About the teacher vs. coach thing. I just want to say that I meant more the general tencency, that there is a student/searcher/novice and a teacher/pandit/guru/coach. Where the latter instructs the former. I see this as the general way it is?
And to be sure, your zen-master does use words when he coaches you, right? Or do you sit and stare at each other in silence? Hehe
Words do exist outside of books
And yes it makes a lot of sense that one needs to practice to get anywhere. Only reading is not a very good idea if one wants to develop beyond certain levels

. But I do think, as stated, that words and books (as well as paintings, music etc.), can help one sharpen and change perspectives that is good to have in one's practical life as well.
That’s also why I started Aikido 4 years ago. And have been doing Zazen meditation, some yoga etc. Because I do find that side to be very important, as you also say.
