While being in that apathic state of mind, emotions can no longer control/affect you which allows you to have good judgement on a given situation and respond accordingly. Thing is, when you practise this it ultimately changes you as a person. How would this affect you normal daily life? Would others on some day say that you have no emotion, they have no clue how you really feel?
Or would this state always be something you can enter and leave at will (which I think btw)?
