Do not be small minded. Do not pray for gourds and pumpkins from God, when you should be asking for pure love and pure knowledge to dawn within every heart.
All will surely realize God. All will be liberated. It may be that some get their meal in the morning, some at noon, and some in the evening; but none will go without food. All, without any exception, will certainly know their real Self.
