The root of all illness is the yearning of all life to return. For the Mother of All Life, the Shechinah, the divine breath, has descended from Her place on high to give life, and She longs to return.
And with that longing She gives life.
If so, at the core of life's pleasure lies pain, an ache that this is not my true place, that I must be higher, somewhere beyond me. But I am not there.
And from that anguish is born life.
And life is good, very good.
