Guard the sanctity of the holy temple with everything you have

So, some say it is not coming to me now that we must guard our heart with all our mind. This is the orthodox tradition. We must guard the sanctity of the holy temple with everything. And to guard it is to exist, to watch and pray. So, to be vigilant to that and not fall for. And it becomes a way of life. So, as we guard our heart, we do not contaminate it with egoistical thing. Then it becomes a more natural way of life. Then when egoic things are brought in through, then there is a taste of your keenness, like something like, I do not want to live there, I do not want to go there.
