What is the spiritual meaning of the blossom?

So that a plant may grow and flourish its roots must expand as well. Lovely though its flowers may be if the roots do not have sufficient soil—do not have sufficient space in which to spread themselves, then the flowers above soon droop their heads and die. And so it is with you. In the matter of tests, the gain is twofold. Not only are the blossoms there to sweeten your way, but more important still, the roots—those firm roots, which mean faith and action—they have also gained in strength and fibre.
