The river of life is a stream of the water of life pouring out of heaven. In the midst of every water molecule is the pisces (fishes). We understand from the knowledge of vesica piscis that "piscis" is a Latin word for fish.
A careful examination of the Yinyang symbol of the Tao in the middle of Bagua reveals that Yin and Yang are two fish and the Tao symbol is the Zodiac sign called Pisces.
Yinyang is equal to a hydrogen molecule, which means that Yin is hydrogen atom and Yang is hydrogen atom.
Hydrogen Atom = 2 Fish (Pisces)
The eight symbols are equal to an Oxygen atom, which means that Bagua is a water molecule. Since there are two fish in a single water molecule (bagua), there are as many fishes in the river of life as the number of water molecules in the universe.
A human hand has five digits, and the right and the left hands have ten digits. Each hand has a thumb and four fingers so that the two hands are equal to two thumbs and eight fingers.
A thumb is a hydrogen atom, the two thumbs are a hydrogen molecule, the eight fingers are equal to an oxygen atom, and the ten digits are equal to a water molecule. Therefore, every human being is equal to a water molecule.
As new infants are born into the world so the water comes out of heaven. And as more people leave the Earth so the water is recycled into heaven.
The river of life is the product of the latter rain from heaven. It is a water cycle. As the rain pours down from the sky and evaporates to form clouds so humans come and go from the Earth. The population of humans on Earth constitute the River of Life.
Since a human being is a molecule of water, and a molecule of water is equal to two fish, the fishes in the river of life are as many as the population of humans on Earth.
Therefore, to catch fish from the river of life is to catch humans.
"Follow me, and I will make you fishers of men" (Matthew 4:19) "KJV"
The translation is "Come with me, and I will teach you to catch people." (Mathew 4:19) "GNT"
You have to use baskets or nets to catch the fish from the river. The net is the network of geometric shapes called space-time continuum, whose base unit is the Foursquare or Perfect Square. And the baskets are spacetime curvatures woven by quantum physicists.
To catch fish means to attract people to yourself and your business. How many fish you caught is determined by how many people are attracted to you and your business. You caught many fishes if you have many customers patronising your business.
You have caught a big fish if a very wealthy and influential person is attracted to you and your business. This fish is more than a thousand fish if he decides to sponsor you and your business.
A big fish is a wealthy investor, a promoter, and a sponsor of your business or cause. He sees a talent and opportunity in you worthy of of investment.
