Trees in mythology

[3] Examples include the banyan and the sacred fig (Ficus religiosa) in Hinduism, Buddhism and Jainism, the tree of the knowledge of good and evil of Judaism and Christianity.

Wreaths, ribbons or rags are suspended to win favor for sick humans or livestock, or merely for good luck.

[7] Numerous popular stories throughout the world reflect a firmly-rooted belief in an intimate connection between a human being and a tree, plant or flower.

Sometimes a man's life depends upon the tree and suffers when it withers or is injured, and we encounter the idea of the external soul, already found in the Ancient Egyptian Tale of Two Brothers from at least 3000 years ago.

Sometimes, however, the tree is a mysterious token which shows its sympathy with an absent hero by weakening or dying, as the man becomes ill or loses his life.

The tree spirits will hold sway over the surrounding forest or district, and the animals in the locality are often sacred and must not be harmed.

[1] In Arab folklore, sacred trees are haunted by jinn; sacrifices are made, and the sick who sleep beneath them receive prescriptions in their dreams.

[1] Early Buddhism held that trees had neither mind nor feeling and might lawfully be cut; but it recognized that certain spirits might reside in them, such as Nang Takian in Thailand.

[1] In Hawaiian tradition, a tree either located at the end of a valley or on a cliff near the sea, is used by the soul as a gateway to the Underworld (AKA Pit of Milu).

The Bodhi Tree of Bodh Gaya is believed to be the Ficus religiosa under which Gautama Buddha attained enlightenment . It is worshipped by Buddhists. The sacred fig is also venerated in Hinduism and Jainism.
