3a.         The advantage of reaching a stage where you won't feel any pain (Ice) is:
              When you reach such a stage where your emotions are fully in your control, then you'll be able to decide when you want to be happy & when you want to be sad (if required). So that when you are in front of others, you can be happy & when you are alone, you can be sad (if you want to be).
              One good outcome of this will be that you won't be contributing to others sadness by being sad yourself.

4a.         I've observed that people generally think that Hope & Expectation are the same thing. But I feel that there is a difference between the two.

              Expectation (about/from something/someone) starts with hope but as it grows, the No/negative part of the answer/event falls behind (in our consideration/focus) & the focus gradually shifts to the Yes/positive part of the answer/event to the extent that the No part is completely forgotten & only Yes remains in our consideration.
              But in the case of Hope, Yes/positive part & No/negative part are always present in our consideration at every point of the event.
