Hare Krishna, Dear Antony,
I think the main reason it happens is because we all want so much to inspire each other spiritually.
So, we try our best to say the most Krishna conscious things we can.
Sometimes though, I think if we express our own struggles, it may help someone else in ways that we have not thought of.
Ways that they would not have been helped otherwise.
For example, this post, and this thread.
It was very very hard for me to express this feeling, and ask for this discussion.
I felt very self-conscious and insecure doing it. I struggled a lot about "should I or not".... even before posting it.
I could have just made a post saying something nice about Krishna instead.
But, as you can clearly see, a lot of people were really interested in discussing this.
Some had problems with this issue also, some others just appreciated the chance for deeper self-analysis or analysis of the concept.
If I had refrained from saying this, (i.e. didn't put myself and my own weaknesses on the line) and just said something more Krishna conscious instead, then no one would have benefited from this discussion.
In fact, this discussion would not have even occurred at all.
That's what I meant when I said in my post "aren't we missing some part of the process".
Thank you for allowing me to talk about it. It was not easy for me at all.
Love,
Navasi

Hare Krishna Prabhuji.
Thank you for your kind comments. As regards your query as regards ourselves as writing instruments, I humbly submit that ultimately it is our intention and motive behind why we are writing that matters. In fact, it is this very intention which woulld even dictate the language, the very flow of words that come to our mind and thence, our fingers drumming on the keyboard.
For example, if I were to write an advice to some friend who's mentioned some problem in some forum, if my ulterior motive is self-glorification, I guess, my very words would indicate so. But if I wrote something with the sincere intention of helping him out and bringing him closer to Krishna (as a devotional service), Krishna will guide my thoughts, my sentences and my very words to that effect. My personal strategy is that since I don't trust myself with even developing and maintaining the 'right' attitude and intention when I write something, I say a quick prayer to Krishna or chant the Mahamantra a few times to guide my thought process so as to come out with something that makes sense and would be of Krishna-Conscious use to someone.
Moral of the story? If you find that something I wrote makes sense? Thank Krishna for it. Found something I wrote that stinks of self-gorification? Blame it on yours truly. :-)
Haribol!
Your eternal servant,
Eternal Muser
