In eastern religion ETERNAL LIFE is attained BEFORE the death of the physical body (which is also the teaching of Jesus). Called: kingdom of God, nirvana, samadhi, etc., etc.
In western religions, eternal life, in heaven or hell, occurs AFTER the death of the physical body (which is incorrect).
The lack of any spiritual or religious experience makes the translation of any spiritual book impossible. The one time SPIRITUAL BOOK of instructions now becomes only a HISTORY BOOK of events and words spoken.
