Life is the biggest question and it is also a dangerous question. Life is so wide open in structure, it is easy to lose your focus and get swept up into someone else's drama. With the life question, anything is a fair subject. You are easily seduced into acts of contaminating the people you are working with. This question takes great personal strength not to contaminate others.
Contamination is a real temptation.
If you are to make progress towards any form of Enlightenment you must do your own work and further you must let others do their own work. Contamination is one of the big sins you can commit with the best of intentions. They are hot and bothered and in listening to them you become very connected to what they are saying. Now it happens to be your turn again. This requires great strength to let other people go their own way.
