Making impartial offerings to the Sangha yields great blessings
If you make an offering to ordinary monastic practitioners with an impartial mind, the virtues you will accrue are no different from the virtues of making an offering to a Buddha. It is their own business if they are accomplished in their cultivation or not. You are simply respecting them as a member of the Sangha Treasure who wears the Buddha’s kasaya robe. It is not that easy to wear the kasaya robe. You should know that in a few kalpas’ time, you won’t be able to see any monastic practitioners in the world.
