The Castle of Fire

Everything that grows naturally, They have tempramental level, Heat provides opportunity to grow, From inner side and outer area. When a person or a naturalthing dies, Water vaporises and heat mixes in fire, When a fire cools down, The remains left as Ashes. But few bones remain left, Fire has no control on them, As a bone of scull and mouth, More harder than a stone. Bones remain safe in soil, No body eats them, Animal, Human and birds, They have no such digestion to glut them. Is a person can use these bones? To protect a body from fire, It is possible to challenge a fire, To breakdown the castle of fire as sun.
