In the Kalingabodhi Jataka, the Buddha taught that,
“An object of reverence reminiscent of the Buddha has no physical basis; it is purely mental. But the great Bodhi tree, used by the Buddha, whether He is alive or dead, is an object of reverence.”
After his Enlightenment, in a show of profound gratitude to the Bodhi tree that sheltered him, the Buddha stood at a distance and gazed at the tree with unblinking eyes for one whole week.
In order for people to pay their respects to him while he was away on preaching tours, the Buddha also sanctioned the planting of a seed from the original Bodhi tree in front of his monastery. In this way, it would be as if he was ever-present.
One of the Bodhi trees in KMSPKS is a scion of the sacred Bodhi tree at Anuradhapura in Sri Lanka and is hence a direct descendant of the original Bodhi tree under which the Buddha attained Enlightenment. It is customary for Buddhists to pay respect to the descendants of the original Bodhi tree.
“菩提”一词为古印度语(即梵文 )Bodhi 的音译，意思是觉悟、智慧，用以指人如梦初醒，顿悟真理，达到超凡脱俗的境界。佛陀是在此树下“成正觉”，此树便被称为菩提树。
