Intentional Randomness

Fjfjfjfjfjfjfjffjfjfjfjffjffjffj*****This is a code

I typed it….Just typed it out of nothing.
But why did my fingers go on “f” and “j”

Why did I start with first letter in caps?
Though it seems it is mere randomness. It is not!
So, let’s analyze it…

I opened the laptop…Stared on the screen for a minute.
Opened word doc and wrote this magical code “Fjfjfhfkaflhflkd”
Tried to do it again now but can’t reproduce!

Until I purposefully look at what I had written and type, copying it letter by letter.

Let me introduce some intentional control and type randomly, ”Ffjfjfjffjfjfjfjfjfjfjffjfj” ...

It comes to something close to the original code.

Any event which happened by “Randomness” can be approximately reproduced by intentional randomness again and again.
“Fjfjfjffjfjfjfjfjffjfjfjfjffj”

The base here “F” and “J” is to be identified.

What’s the base of the stars, the planets, the light, sound,
These fucking objects which may have occurred by randomness.

Can be intentionally reproduced by intentional randomness.
Identify the base!!!(It should be ideally not more than two “things”)
