I read this part about deaking with drowsiness :
The dispelling of dullness and drowsiness calls for a special effort to arouse energy, for which several methods are suggested: the visualization of a brilliant ball of light, getting up and doing a period of brisk walking meditation, reflection on death, or simply making a firm determination to continue striving.
So i would like to know how reflection on death can help drowsiness ? and how to do it ?
and a mini question - where should i visualize the brilliant ball of light in my body or outside ? should i visualize it is warm also?
