Sometimes we simply do not give ourselves enough time to be still, alone, and just think of nothing. Our lives are a busy mish mash of things we are trying to cram in, when sometimes we just need to STOP.
Stillness reveals the secrets of eternity
Eternity embraces the all-possible
The all-possible leads to a vision of oneness
A vision of oneness brings about universal love
Universal love supports the great truth of Nature
The great truth of Nature is Tao
Whoever knows this truth lives forever
The body may perish, deeds may be forgotten
But he who has Tao has all eternity
This is the quote in context. What it is saying is that in order to be at peace we need to be at one with ourselves and live in this moment, not distracting our mind with thoughts other times, whether that be past or future.
So, in today, find yourself a moment to stop, and think of nothing. Peace, inner peace, will bring harmony and happiness.
