Inspiration behind Cedar Tree

"The heart's affections are divided like the branches of the cedar tree; if the tree loses one strong branch; it will suffer but it does not die; it will pour all its vitality into the next branch so that it will grow and fill the empty place."

--Khalil Gibran

"....the cedar tree symbolizes strength, and in Lebanon, the tree serves as an important cultural symbol for that reason. Poets and artists have conveyed the tree as a sign of strength and eternity, especially given the tree's endurance through tumultuous periods of history."
