In this book Divine Heritage of Man, Swami Abhedananda explores the dual nature of humanity, describing it as a "state of transition" between the animal and the divine. He posits that while human expression often leans toward animalistic instincts, the core of every individual—the soul—remains a perfect image of the Divine.

The Swami uses the metaphor of twilight before daybreak to illustrate this evolution: the darkness of our lower nature gradually gives way to the "glorious sunshine" of supreme wisdom. Ultimately, the text emphasizes that despite the diversity of individual thoughts and actions, every soul reflects a single, universal Divine Being. We are, at our essence, holders of infinite potential and blessed qualities, waiting to transcend our earthly limitations.
