As the Sufi Thoughts teach, there is one moral, there is one virtue, which is Love. Particular virtues arise from the qualities displayed by love in everyday affairs. Thus arise courage, mercy, kindliness, compassion, adoration, friendship, fidelity, charity, brotherhood and many other virtues. Yet all are aspects of Love.
So soon as the heart ceases to be active, so soon as mind gains control over will, the Love-Life energy from the higher spheres no longer touches the personality. This brings about the reign of sin over one. This is the fall of man, true of Adam and true of all his descendants.
