A drop of essential oil.
The essence of the leaves and flowers from which it was derived.
A drop in a small amount of carrier fluid results in a strongly scented potion.
The same drop in a vast body of water is diluted so as to become undetectable.
The mind is the same way.
Swimming amidst a sea of thought, distraction and task it becomes fragmented and unable to keep up.
Calmed, focused and concentrated it reaches its true state.
One emitting a most glorious scent.
Amidst the silence resides the essence of the mind. That of reflection upon truth and Love and Compssion.
And compassion again.
