For I, rasta has always been based on the idea that Man can only understand the world by directly communing with God, using the Tree of Life as a holy sacrament.

Rasta today are the living prophets.
Jeremiah, Isaiah, John the Baptist, Jesus, and Samson and others
did likewise. All observed the vow of the Nazarite from the Book of Leviticus:
To not cut one's hair as a promise of dedication to God and Truth.
