Knowing that everything would be finished one day, makes me feel very disturbed. How do I come out of it?
The temporary nature of things around you should enable you to calm down, and settle in deeper within yourself. It is good if it disturbs you, if it wakes you up from your slumber (of ignorance). But I tell you, hold on to it and go deep within. You will find that a higher horizon opens up within you where you feel invincible; where you will experience that you are not this finite body but rather you are the infinite consciousness.
