What does the poem fear no more by shakespeare mean?

It is of sound counsel offered to one who seems to have arisen above the bounds of fear. Fear no more. Be freed from shackles of fear, of defeat and pained oblivion. It also reures, comforts with a blessing, that none be able to harm, or cause affliction by any means of sorcery or contradiction. It urges to live free in spirit, and be renowned to beyond the grave, an immortality gained by gallant deeds, and great feats of accomplishment. It urges shedding of fear of scandal, implying the recipient is nobler in love than many great professors’ of poetic odes. The mountains be as stepping stone to dreams and great oaks as strand within the hand. Written by one who loves much, maybe a Father to his child. Or surely one he loves with deep devotion to set free on higher planes upon a journey inferred into his hearts
