Listen, my heart: love God ceaselessly
As the fish loveth water:
The deeper the water
The happier and more tranquil the fish.
God alone knoweth the suffering
Of fish separated from the waters.
~ Nanak, Sufi teacher
The tree of life is one's inner axis that grows from the depths of the earth and reaches to the heavens. It connects together the primal opposites of the temporal and the eternal. It is life lived from the "still center of the turning world" and it embraces the deepest human mystery: that we are eternal beings living in a world of time.
