After writing a long discourse, pooring my heart to it, it went down into the nihil of cyberspace through an unfortunate software error (browser timeout).
But the thoughts resonate on the pranic and mental planes, so not all is lost, and for my not so small ego, it is a good lesson in humility, equanimity and non-attachment.
I'd shortly conclude that The Guru is everywhere, if we are able to recognize It/Him/Her, both inside and outside.
Our karma is the best guru, and when we get a glimpse of the wisdom behind it, through intuition, what other sign or guidance do we need ?
Inside, outside ... can we really know ourselves without relating to what life brings us ? Are we separate from the world ? Where is the border ? Where do I stop, and where does the world begin?
We do not need an authoritative guru who guides us with an iron hand, as we do not need the Old Man with a white beard sitting on the clouds.
We need teachers, brothers and sisters, husbands and wives, lovers, children and parents, collegues and adversaries. We need them all, and they all need us.
