He was a real person. He was pure Emes. Whatever he said, was truth, his actions were very real, he was very dedicated to whatever he set his heart and mind to, despite unspeakable pain, and he served Hashem with all his might even when things were difficult. His Emuna and Bitachon was incredibly strong, his great willpower to live pulled him through 10 difficult, painful years. . He believed even in the most difficult time against Doctors, that he will get better. Yet he didn't view these years as painful. He viewed them as 10 years full of opportunities to spread Yiddishkiet everywhere and to everyone he encountered, filling this world with light as he helped usher in Moshiach closer. May we see the results of his hard work, and may we be immediately reunited with him together with Moshiach now!
