We are primarily governed by the generation, depletion n conservation if energy flowing thru our bodies n minds n spirits.
Most of our energy is wasted rather than spent in mundane affairs, thoughts n words. It takes a dip when we are not able to conserve it or generate it to replace the one that is wasted.
To feel energetic n upbeat we must plus the holes that leak it by being mindful of our being.
Just a fraction of a second before taking the lid off is enough to save it. By just using it optimally n replenishing the one used, we do ourselves a great favour.
This is possible by just meditation n silence n patience. Acceptance of what is, is also of paramount importance in this regard.
