There is no such thing as effortlesss effort. Things don't come to us just like air. Good things don't come to us that naturally. We naturally have them in us, but we have to work very hard to arouse them. Our mind is like water.
Water always goes to the lowest place.
Similarly, our mind drags us into the lower state of things. To lower, base ideas, to lazy practices and so forth. That way, we will go down the drain with all this rubbish in our mind. Our effort is to get rid of this rubbish. And we must turn up the effort, we must make the effort to overcome this.
