Tragedy and suffering are real, extremely serious and very painful. Ideas and understanding do not always make the pain bearable, and even our greatest sages felt this way:
Rabbi Chiyah, the son of Abba became ill, and Rabbi Yochanan went to visit him. ‘Do you accept your sufferings?’ He said to him, ‘Neither they nor their reward.’At some point though, time will do what no human or idea can, and the pain will pass. It is then that the sufferer will need to be able to put the events into perspective, to be able to go on with life in a positive way. Perhaps the ideas in this book and the many like it will facilitate such a perspective, and stimulate positive growth.
