At all times, do not lose courage in your inner awareness; uplift yourself, while assuming a humble position in your outer demeanor. Follow the example of the life and complete liberation of previous accomplished masters (siddha). Do not blame your past karma; instead, be someone who purely and flawlessly practices the Dharma. Do not blame temporary negative circumstances; instead, be someone who remains steadfast in the face of whatever circumstances may arise.
In brief, taking your own mind as witness, make your life and practice one, and at the time of death, with no thought of anything left undone, do not be ashamed of yourself. This itself is the pith instruction of all practices. (Heart Advice)
