Summary
This quote by Robert Browning suggests that life is essentially a testing ground for the soul's resilience and endurance. It implies that the purpose of existence is to face difficulties and challenges in order to gauge one's inner strength. By viewing life as a mere "stuff" or material for testing, Browning implies that it is through these trials that the soul grows and develops. This perspective encourages us to embrace life's challenges as opportunities for personal growth and a catalyst for strengthening our inner selves.
