Sometimes called the tree of life. Always associated with religious belief. It symbolizes Divine power and perpetual life. It has furnished more different art motives than any other object and is almost omnipresent in Persian prayer rugs. The palm signifies a blessing or benediction, the weeping willow stands for death, and the cypress, while being an emblem of mourning, in its perennial freshness and the durability of its wood, is also a very practical symbol of the life to come. It is an Oriental custom to plant cypress trees on the graves of the dead, to place its twigs in the coffins of the dead, and to use its branches to indicate the houses of mourning. In India the cocoanut palm is considered "the tree of desire" or one that fulfils all desires. Its stem serves as a pillar or beam, as a water conduit and as fuel; its leaves supply mats for roofing the houses; its kernel supplies oil; its shell makes water bowls, and the oil of the shell is used as an external application in certain skin affections, etc. It is all useful and supplies all the primitive wants and therefore was much cultivated by the Rishis (Saints) of old, who called it "kalpa taru," literally the tree that supplies all desires. Its presence therefore is auspicious.
