So here as in many others commentaries I will take the chance to talk about the refuge, because the discipline fundamentally in the buddhadharma, the most precise and most concise form of discipline is disciplining oneself by taking refuge to the Buddha, Dharma and Sangha. And I don’t want to go too intellectual here but it is important if you are serious in pursuing this spiritual path you also take the vow of refuge such as what we did just now before we began our teachings we did Sangye cho dang tsok kyi chog nam la, jang chub bar du dag gi jin gyat su chi, so we take that kind of vow. Vow is important. If you have a vow you accumulate merit lot faster. I will give you one example. Let’s say we human beings we have not taken a vow. Okay lets say many of us we have not taken a vow. Many of us, many human beings don’t take vows of not killing. Not killing. So they don’t kill, see people don’t go at this moment, this morning maybe, outside, inside here we don’t go around killing people or killing animals. But if you have not taken a vow it doesn’t mean that you are accumulating merit. You are not killing anybody because you just don’t have a time or you don’t have the energy or you don’t have the weapons to kill, it’s too boring anyway. It’s too hassled, so much hassle so why do it. So you don’t have a bad karma, you don’t have a good karma, you have nothing. You are just not killing, that is all. But for someone like here maybe most of you, like the Bikshus here, you have taken a vow, I shall not kill. As part of the, let’s say, part of the vow of refuge. From then on, once you have taken the vow, from then on, every second every moment when you don’t kill such as while you are dozing off, you are accumulating the merit. And this is why the vow is quite important.
