The ignorant runs after pleasure, Sinks into the entanglements of death... the wise seek the undying, And hence found himself.
The knower of self, the self, which is here, is hereafter; Hereafter is here. He who thinks otherwise, Wanders from death to death.
The self is eternal. So why the fear of death. Here, in poetry, I am encouraging you to chase the inner you (the undying) instead of the worldly stuff (the pleasure).
