Pain is a reminder that life that looks outwardly amazing is actually hollow from inside. Pain and suffering was not intended by Divine but they arise as an evolutionary need. If things stay static they would not have pain. Equally if man progresses in complete alignment with his soul need and the Divine Will the need of pain would be minimized. The moment earth takes a step ahead; pain arises in us due to attachment to the past ways and habits of life and thoughts and actions.
