To love and be loved is to feel the sun from both sides.
What makes this observation peculiar is its suggestion that mutual love creates an *asymmetry of warmth*—that giving and receiving are not mirror images but rather complementary actions that together produce something neither could alone. Most people think of love's reciprocity as simple balance, but Viscott understood it as an optical effect: you're not just warmed by the sun, you're enclosed by it. When a parent stays awake through their child's illness while that child, years later, cares for them in old age, both experience something larger than devotion flowing in one direction—they've each felt the heat from opposite angles, which changes everything about what warmth means.
