Sit, Seat
There are two people under a canopy on the dirt. What are they doing? It's a thing called sitting. They're using the dirt as a seat for their butts.
Imagine how it feels sitting on dirt. Is it comfortable? Probably not. Maybe you feel a little uneasy about just sitting on plain dirt. Try to recall this feeling whenever you encounter this kanji.

You shake your head in disbelief. People can't just sit on dirt, in fact, according to a Czar (ざ) you met recently, they shouldn’t be sitting at all!
This Czar you met is ruthless and has formally banned sitting for everyone, even on dirt. Imagine the excruciating pain of never being allowed to sit, ever; even on dirt. What a cruel Czar.
