Why do we find it so difficult to believe the truth of impermanence and the uncertainty of the time of death?
This question have crossed my mind countless times. here's a little of what i've thought of ...
Impermanence can be observed on a daily basis..it doesn't need any clairvoyance or special scientific tools to show us.
Why is it so difficult for us to believe. Well, Buddha is undoubtedly right about teaching impermanence and he also taught on ignorance, the root of all our sufferings.
Just knowing is not enough and we will continue to experience the difficulties to believe in the dharma because we do not continuously contemplate on the disbenefits and benefits of the way we think, the way we live. Thus on a daily basis, we do not rehabituate/infuse our thinking with the dharma we have learnt....
I read somewhere before from the zen tradition that ignorance is defined as assertion of self will.
I guess as long as we assert self will, we make our own reality. Therefore we create our own obstacles to believe the truth.
Buddha taught us that we must question the teachings for ourselves. I find that it is sad that often times, we question so much that we get no where. In the gelug monasteries that I know of, it is well known that monks engage in daily debates. They are taught how to debate and it is guided on a daily basis by the debate master. I find lay people's "debates" more as arguments instead of a form of learning...a way to further reinforce our own ignorance and self will!
