'Leaves' signify truths according to the different kinds of tree. 'The leaves of the olive tree and vine' signify rational truths from celestial and spiritual light. 'The leaves of the fig-tree' signify rational truths from natural light. 'The leaves of the fir, poplar, oak, and pine' signify rational from sensory light. The leaves of those last trees excite terror in the spiritual world when they are agitated by a strong wind. These are the trees mentioned in Leviticus 26:36 and Job 13. 'Leaves and blossoms' signify the truths of faith.
