Question: What do these beings do? Do they have a lifespan? We have a physical lifespan. Are they immortal? Do they live forever?

Sri Chinmoy: They can live as long as they want to. We cannot live as many years as we want to. Even if we do not want to, tomorrow we may have to die if it is God's Will. In their case they can live indefinitely. Again, if they are bored, if it is too much for them, if their life is too long, then they may die.
