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.
All of you knowing now, Tthat the Buddhas, the Teachers of the Ages, In accord with what is peculiarly appropriate, have recourse to expedient devices, Need have no more doubts or uncertainties. Your hearts shall give rise to great joy, Since you know that you yourselves Shall become Buddhas.
If my happiness at this moment consists largely in reviewing happy memories and expectations, I am but dimly aware of this present. I shall still be dimly aware of the present when the good things that I have been expecting come to pass. For I shall have formed a habit of looking behind and ahead, making it difficult for me to attend to the here and now. If, then , my awareness of the past and future makes me less aware of the present, I must begin to wonder whether I am actually living in the real world.
Thus all things are subject to death, sorrow and suffering. I became aware that I too was of the same nature, the nature of beginning and end. What if I searched for that which underlies all creation, that which is nirvana, the perfect freedom from unconditioned existence?
The universe that we inhabit and our shared perception of it are the results of a common karma. Likewise, the places that we will experience in future rebirths will be the outcome of the karma that we share with the other beings living there. The actions of each of us, human or nonhuman, have contributed to the world in which we live. We all have a common responsibility for our world and are connected with everything in it.
Let go the past, let go the future, and let go the present (front, back, middle). Crossing to the farther shore of existence, with mind released everywhere, do not further undergo birth and decay.
Giving up attachment to the world does not mean that you set yourself apart from it. Generating a desire for others to be happy increases your humanity. As you become less attached to the world, you become more humane. As the very purpose of spiritual practice is to help others, you must remain in society.
