Future prediction and Incarnation of Lord Hanuman

First story is of Amba; when she was 14 years old, she had gifted a self-written poem to her father, wherein she predicted her death at the age of 21; this poem turned out to be true, and she died at 21. The second story is of Chennai's Washer man, a great believer of lord 'Hanuman', whose prayers for sons like 'Pawan Putra' came true and he was blessed with three sons, looking like troglodyte. These three brothers were taken care of by their elder brother Murugeshan and his wife Murugeshwari.
