Most self help books and websites address all the problems at the level of the mind, but when you talk about enlightenment, you need to transcend the mind itself. I read that Buddhism does not encourage the use of the intellect at all. I thought to myself “Oh, how can that be, are all those guys dumb or live life’s that are highly under stimulated and simplified etc, Why would someone agree to that, the greatest gift we have is our thinking ability”. But then, I later realized that their idea was to transcend the mind itself. Their logic is like “the only way to win the game is to not play at all”. The fundamental nature of the mind is the “wanting state”. No matter what you do, what you accomplish etc you would always remain in that state. So you need to sort of move into a higher dimension. Their lives were kept simple, abstaining from sexual activity etc but this was not exactly a total sacrifice. The reason for that was: Sex is one of the most powerful attractive forces at the level of the mind. So in order to transcend it, you would rather not have this powerful force tightly holding you”. And about the simplicity of their life, the reason for that is, we erect our whole sense of self from memory. If this is too rich and complicated filled with varied likes/dislikes/passions/aversions it becomes difficult to transcend it. When you minimize your likes/dislikes/wants etc. your self is fairly simple and it makes the transcending part much easier. Generally if you completely overcome the fear of death, you would overcome all fears since death is the root for all fears.
Another question asked is that, does an enlightenment person ever suffer? The question of suffering/pleasure is a qualitative judgment at the level of the mind. When you go beyond that, the question almost becomes irrelevant. Enlightened people are in contact with the instrument of life force itself. They would always be like light and pass through any situation seamlessly including death. They would be aware of the mind and its conceptualization but they have the choice to turn the mind off. The consciousness force with them is like an iron ox and even death would not scare them.
