As long as we are involved with external appearances, we have to carry the burden of doubts and weakness of faith. We will not be able to get rid of involvement in unnecessary things. Faith is like a live volcano. No seed will sprout on such a volcano. Doubts are like seeds. If the doubts multiply, it means that your faith is weak and unstable. It is like an extinct volcano. If your faith is strong, no doubts will crop up. Where there are doubts, there can be no faith.

- Divine Discourse, July 24, 1983.
