The icon "Tree of Life" is quite rare, its second name is "Spas True Vine".
It depicts Jesus Christ in the middle of a vine with branches extending from the central pillar. On them are the Mother of God and the disciples of Christ.
The tree symbolizes the Church, Holy Scripture.
Jesus Christ is placed in the center, representing the ideal image of a Christian. And the apostles close to him symbolize the people who are closest to him and know the faith. Also, small leaves are depicted on the branches, which in turn symbolize other people whose task is to spread the Christian faith.
The tree, like the Church, does not stand in one place, but is constantly evolving. And each person should make his own contribution to this development. In particular, to spread love and wisdom among all people.
Also, the icon is a symbol of fertility and immortality (like an ever-growing Tree).
