I had gone to a temple recently... there I read the following:
Whether you stand still or move, your days diminish.
Then grieve only for yourself, why grieve for anything else.
These above lines had the magical effect of relaxing me. They are translated from some religious text, but the meaning is absolutely clear.
In the recent past I have tried to become emotionless. To remove all emotions from my heart and mind. To attain perfect objectivity.
Why do we indulge in emotions and have thoughts/worries associated with those emotions?
Nothing is going to last forever and the sands of time will cover all.
