The flowers of a tree signify spiritual primitive truths in the rational man. The budding and fruits of a tree represent the rebirth of man. The growing green from the leaves represents the first state, the blossoming the second, or the next before regeneration, and the fruits the third, which is the state itself of the regenerate. Hence it is that leaves signifies things of intelligence, or the truths of faith; for these are the first things of the rebirth or regeneration, but the flowers [or blossoms] are things from wisdom or goods of faith, because these proximately precede the rebirth or regeneration. The fruits signify things which of life, or the works of charity. Flowers, as in 1 Kings 6:29-32, signify spiritual natural good, which is the good of the ultimate heaven. Flowers and flower-gardens signify scientific truths.
