Lion & Jackal are complementary to each other.

-  A large army of jackal can won the battle under the leadership of only one lion.

- But A single jackal is itself enough to bring destruction/bad luck for large army of lion.

Maybe one do not satisfied with other's opinion,  but former should made efforts to represent the latter one among public discussion. 

When you have faith, everything is possible.
