At a personal level, as a Buddhist practitioner, I deliberately visualize and think about death in my daily practice. Death is not separated from our lives. Due to my research and thoughts about death, I have some guarantee and some conviction that it will be a positive experience.
Do not accept what you hear by report, do not accept tradition, do not accept a statement because it is found in our books, nor because it is in accord with your belief, nor because it is the saying of your teacher. Be lamps unto yourselves. Those who, either now or after I am dead, shall rely upon themselves only and not look for assistance to anyone besides themselves, it is they who shall reach the topmost height.
Let yourself be open and life will be easier. A spoon of salt in a glass of water makes the water undrinkable. A spoon of salt in a lake is almost unnoticed.
If the situation was such that there was only one learned lama or genuine practitioner alive, a person whose death would cause the whole of Tibet to lose all hope of keeping its Buddhist way of life, then it is conceivable that in order to protect that one person it might be justified for one or 10 enemies to be eliminated if there was no other way.
One who does not rouse themself when it is time to rise, who, though capable, is full of sloth, whose will and thought are weak, that lazy and idle person will never find their way to true knowledge.
He whose longing has been aroused for the indescribable, whose mind has been quickened by it, and whose thought is not attached to sensuality is truly called one who is bound upstream.
