In addition to fear of the other, the fear of death was a product of left-brain perception that denies cyclical time and instead sees time as linear. In linear time the end is no longer connected to the beginning. The end is the end, and death is the final conclusion of life. Life and death are not seen as the two alternating phases of cyclical existence, but instead are viewed as warring opposites. In a cosmology where death is linear and final, not cyclical and renewing, death is the ultimate terror.
