Tree of Life
Ichthys
Lotus flower
The state of enlightenment is generally used in Buddhism (symbolized by a lotus flower). God’s definition of enlightenment is: You know the truth, the whole truth and nothing but the truth.
The truth is symbolized by the tree of life (instead of the Bodhi tree where Buddha reached enlightenment) and the Icythys. In other words, Jesus is the truth, the way and the life.
"The Icythys or ichthus, from the Greek ikhthýs ("fish"), is a symbol that resembles the profile of a fish. It was used by early Christians as a secret Christian symbol and now known colloquially as the "sign of the fish" or the "Jesus fish." ΙΧΘΥΣ (Ichthus) is an acronym/acrostic for "Ίησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ", (Iēsous Christos, Theou Yios, Sōtēr), which translates into English as 'Jesus Christ, Son of God, Saviour'" 5.
