When our attention and awareness aren't directed towards the activity taking place within the mind itself, we tend to experience our level of happiness as a result of the situation we are in or what we are currently doing.
But in reality, these are not directly in charge of how we feel, but rather whether we are experiencing a sensation of desire and to what degree it is satisfied.
To desire and to experience the relief that follows the fulfillment of it isn't possible at the same time. This means that if the desire goes on and isn't satisfied, we become locked out of our own happiness. Therefore, in some cases, the only way to release tension and return to our happiness is to directly end the desire. Which means to end the seeking.
This is often the hardest part of the process because it requires us to stop trying to attain something we feel is missing and is necessary to our wellbeing.
But as we slow the movement of our compulsive thinking occupying our attention, the ever-present light we already carry begins to shine through us again and we can begin to feel content with where we are without the desire and need to change anything.
