How should I view others sufferings I cannot affect? Through Vipassan meditation one can learn how to guard ones mind against externalities and not be affected by emotions. I believe that trying to follow this meditation to view the world from an unemotional state with actions not guided by emotion would definitely help me to be more aware and more awake, as well as have a happier and calmer mind. However, my concern is the following:

Does not letting externalities affect you mean ignoring externalities? I know that this meditation will help me feel better, however is it morally right to ignore the suffering of the world so that I could feel better?
Firstly, meditation isn't about becoming an unemotional robot, it is about living a life not being control by your emotions, it's completely different! You can either be the master of your mind or the slave. 

There is a big difference in ignoring the worlds suffering, compared to understanding the root cause of all suffering. As for the suffering of the external world, i would recommend studying and contemplating the 4 Noble Truths. Once you realize that ignorance is the root to all suffering, then you will view the world completely different.

Also if you want to help the suffering of the external world, i would suggest not increasing the suffering of others, that would be a good start, and to achieve that, it would be for you to continue your practice into freedom, then you can be an example for others!!

I hope i have been of some help.

Metta.
