The great oceans are made up of many single drops of water, which come together to form one body of water. This is much like both our individual practice as well as the assembly of the Sangha and makeup of a temple.
We each have our part to play and the success of the whole depends upon each person.
In our individual lives, it is the accumulating of many small efforts on a day-to-day basis that results in the accumulation of an enlightened life manifesting Buddhahood. When we look at our small efforts we may not see the potential of the accumulation of those efforts, just as we don’t see the ocean in the single drop of water.
