What is supremely important is to be free from contradictions: the goal and the way must not be on different levels; life and light must not quarrel; behaviour must not betray belief. Call it honesty, integrity, wholeness; you must not go back, undo, uproot, abandon the conquered ground. Tenacity of purpose and honesty in pursuit will bring you to your goal.
Each day, we wake slightly altered, and the person we were yesterday is dead. So why, one could say, be afraid of death, when death comes all the time?
