Question: When the dinosaurs ceased to exist, did their souls also cease to exist, or are there people now on earth who were once dinosaurs?

Sri Chinmoy: Some souls did not want to take any more incarnations; they did not want to make progress on the earth-planet. So they entered into the soul's world and remained there. Again, some souls wanted to be part of God's manifested creation. They wanted to make progress on the earth-planet, so they entered into the process of evolution and started taking birth in different forms as animals and human beings.
