Arcana Coelestia #98
98. Verse 8 And Jehovah God planted a garden in Eden, from the east, and there He put the man whom He had formed.
'Garden' means intelligence, 'Eden' love, 'the east' the Lord. 'A garden in Eden, from the east' therefore means celestial man's intelligence which flows in by way of love, from the Lord.
Rivers
'Rivers' or 'floods' signify temptations. 'Rivers' signify truths in abundance serving the rational self, and so, the understanding, for the purpose of doctrine and life.
In Isaiah 43:2, 'rivers' and 'waters' signify difficulties and falsities.
