Everybody has his own personal history and stuff to deal with, right. I experience trust or faith is very important to develop. Without faith one will fear life and death. Thinking about dying is very important because one can imagine that one has overcome a lot of kilesa’s, but at time of death, things can turn out to be differently. Strong forces (anusaya) will probably take over.
But faith is not easy to develop and is lost easily. There are a lot reasons to loose faith. Faith in people, faith in life, faith in your own mind, faith in institutions, faith in body etc. Loosing faith in ones own mind is very difficult to overcome is my own experience. I keep practising and do not give up taking refuge in Buddha, Dhamma and Sangha.
