One’s inner fire can become a towering inferno if it’s not known what causes it to ignite. This is the selfish fire of desire and its fuel will have to be removed to prevent one’s fire from igniting.
It can be said that “the world is on fire” and all one needs to do is turn on the news to see how true this is. The cause of why there’s a fire needs to be examined if one isn’t to succumb to the selfish flames of desire, although it’s not the world that needs to be examined, it’s one’s own driving energy that needs to be examined. What one’s energy is focused on is what ignites the fire, greed, hate, self satisfaction, envy, lust, and so on is the energy of a restless mind and this is what causes the inner fire. Some fires are raging and some are smoldering, but having awareness that they’re there is the key in not only extinguishing them, but removing the conditions that allows them to ignite to begin with.
This inner fire is mostly because the restless mind (selfish desire) is the norm and there’s nothing in place to prevent it from igniting. Any fire needs certain conditions to be met to ignite it and it’s the same way with a mind that’s on fire (restless). If these certain conditions aren’t met, the fire can’t ignite. Fire needs fuel (energy) so it’s important to be aware of when the fire starts to see if it’s going to be given more fuel to grow or if one has the necessary awareness to remove the conditions that are causing it. You can just extinguish it, but this may not prevent it from reigniting, it’s only when the fuel of selfish desires (the conditioning in place) are removed that it will be impossible for one’s fire to ever ignite.
