I'm sure Balaguero was trying to create a powerful allegory for God, motherhood and faith with his short film Alicia, but none of that is very important. What's important is, the impact 5 minutes of film can have on a person. The visuals are nothing short of spectacular (particularly the opening "hemorrhage", and "feeding" scene). I'm not sure how easy it will be to track down a copy of Alicia, but I recommend you try.
