Four Questions The Mature Human Being Should Ask

“The living entity is ignorant of his origin. He does not know why this material world was created, why others are working in this material world and what the ultimate source of this manifestation is. No one knows the answers to these questions, and this is called ignorance. By researching into the origin of life, important scientists are finding some chemical compositions or cellular combinations, but actually no one knows the original source of life within this material world.” (Shrila Prabhupada, Shrimad 4.25.33 Purport)
