Answer: To do this, we must work together to fulfill one mission. Suppose we get into a submarine and go out to sea. It is going to be a difficult and dangerous experience in which everyone depends on everyone else. I have a very strong feeling that one person’s mistake or another’s malfunction means that we are all going to drown.
We are in a middle of big ocean, thousands of miles away from any shore, deep under the water, and suddenly one of the valves goes out of order. Now it is impossible to pump the water from the ballast tanks. Together, we try to find a solution to resurface.
In such circumstances, in this state, we have to ascend to unity.
