Here is an intimate letter from Nichiren who recently lost her husband (a Samurai), to encourage and support as well as educate her on the nature of her husband's tremendous influence on her life; but also in the nature of our lives to be attached to physical identity rather than our true timeless entity of enlightenment. He identifies, for instance, that the 'manifestations' of 'hell' and sufferings all are manufactured and nurtured from internal states of mind. So demonstrating that it is totally within our human grasp to convert and use these states in order to transcend and arise our Buddha nature through the conversion from Buddha .manifested body to Buddha reward body and ultimately realize the Buddha Dharma body.
