If you continue in the realm of intellect, you will become entangled and lost in more and more concepts.
At the highest level, in reality, nothing is. At the worldly level, everything is.
You may adopt any concept that will make you happy but remember that it is still only a concept.
Reality makes the present so vital, so different from past and future – which are only mental.
The mind craves for formulations and definitions, always eager to squeeze reality into verbal shape.
