There is a fish called Bubbles. Bubbles is ignorant and does not know he is in water. Bubbles is not concerned with swimming with the others. Instead, he begins to meditate alone, in isolation. For many years, he closes his eyes and meditates.
One, rainy Tuesday morning, Bubbles has a scary experience and realises that he has actually been swimming in water his whole life. Only through observing the internal, has he come to understand the external. Bubbles is no longer ignorant, he has now become wise.
