"World" is an extremely vague term, and those who write love letters are redefining "world".

What is a "love letter"? Let someone start by writing 50,000 or 500,000 words...

A love letter is not a "book" but rather like a "letter", and also resembles "trust"...

Who is the "first" in your human life?

Who is the "only" in your biological life?

50,000 words are not enough for a person to ‌detect that "imagination" is a maze but not an enigma...

500,000 words are also insufficient for someone to gaze at "intuition" beyond a moment... 

5 million words, piled up or spliced together, are optional (existence or non-existence), can be still or moving, let it pass with a smile...

Are 5 words simply 5 "drops"? 

Let someone give the little hedgehog one word—Love-Letter (abbreviated as "LL").

Let someone give the little turtle one word—Intuition-Imagination (abbreviated as "II"). 

Let someone give the husky one word—Sheer-Structure (abbreviated as "SS"). 

Let someone give the Sweetgum tree one word—Love-Thinking (with no abbreviation or nickname).

Which word might be given to a tiny bottomland in a silent corner of a vast blue sea? Love-letter-lounge ("LLL" for short).

A biological life that lasts but a moment is just a life.

A human life that passes with an unintentional smile is still a life.

"Love Letter" is a word that caresses someone's face like a gentle breeze; it can also be a fleeting moment, a world like a drop in the ocean‌, or "the first sheer-smile of life that has both a gurgling sound and a murmuring echo", or "the only intuition-journey in life that can meticulously relax both rationality and sensibility"…

An Intuition-Journey is like a Love-Journey; what has been experienced is what has been vividly lived.

To laugh, or to be laughed at—both are forms of relaxed Love-Thinking.

Do LL or LLL both trust II and SS?

Love-Bar is both vague and precise, unhesitatingly waving at the enchanting maze through the sheer curtain of Intuition-breaking Drops...

Love letters are to splice together one impossible world after another, and leave behind a shimmer of possibility that would be most incisive and vivid.
