Gaffes

When the young monk finishes inscribing the Heart Sutra on the floor and falls down exhausted, the inscriptions below him change between shots (even though he is lying motionless). In one shot, the inscriptions he is lying on have been painted; and as he wakes up, the paint is gone.

When the old monk holds and strokes the cat, the cat's position changes between shots.

After the cops take the young adult monk away and the old monk is standing on the monastery watching, a fine monofilament can be seen pulling the boat, which is ostensibly floating on the current, back to the monastery.

When the middle-aged man comes back to the monastery after murdering his wife, he is seen taking the rowboat alone to shore to vent his anger. His former master inexplicably appears behind a rock on the shore watching him, despite his clothes being fully dry and the only boat having been already taken.

When the woman is pushed in the water and climbs on the boat, she has lost her shoes. When she returns to the platform after the romantic encounter, she has her shoes on again.
