Mind parasites and the hijacked life

Sitting one day on a shaky kitchen chair, sipping on a cup of mint tea and chewing on a soft piece of buttered bread, we realize, all of a sudden, that we are looking but not seeing, chewing but not tasting, sipping but not smelling the aroma of the herbal tea.
We feel as if a replica of us had taken over, and morphed our life into a dull set of mindless routines.
We feel that our life has been hijacked by an incessant stream of random thoughts.

Our mind gets misappropriated then subverted by randon, irrelevant, and often destructive thoughts that are sometimes called "Mind parasites". 

They have the same effect as the "conventional parasite" that affects the physical body, sapping its energy and rendering it fatigued, feeble and in some extreme cases bed-ridden.

We need to learn to laugh at these aberrant and inane ideas and images that barrage our mind.

We can't stop them, because we are a receiving station, soaking up ideas, emotion and thoughts from our immediate environment, but we can scoff at them by cultivating a happy contenance, which is the best shield against these harbingers of doom and gloom.

A happy person brushes off derogatory comments and unfavorable thoughts with elegant ease, while a person with a sad contenance tends to latch on to them because they amplify and sustain a miserable state to which a lot of people, unfortunately, are addicted to.
