Seems like the meaning behind it could be interpreted a few different ways, depending on your perception. I'm interested in hearing what others think. I can definitely relate to the amount of bhakti the monk has!
HI Trip well I'm sure there is more than one interpretation of this but here's mine.
The fish represents his ishta that something that always seems just out of reach he chases it and chases it but the harder he chases it the more it goes just out of reach. Then he just lets go joins the flow with it opens the door and just lets it in.
I think its beautiful a perfect example of the path we are all striving on
I'm glad you enjoyed the film and agree that the interpretation lies in the eye of the beholder. My personal interpretation is pretty much spot on with the one Azaz gave.
