In seventh heaven

Origin

Ancient cosmologies, particularly those found in Jewish, Islamic, and Christian mystical traditions, often depicted the heavens as a series of ascending spheres, each more divine than the last. The 'seventh heaven' was considered the uppermost and most sacred layer, the very dwelling place of God, the holiest angels, and the souls of the righteous. To ascend to this ultimate realm was to achieve the pinnacle of spiritual perfection and indescribable bliss. This profound religious imagery of ultimate divine joy eventually transcended its theological origins, entering common parlance as a powerful metaphor for experiencing any supreme and overwhelming happiness, whether spiritual or earthly.
