Why do skilled traders tend to become more compassionate by the end of their trading?

The essence of trading is extreme competition, killing, and attack.
Compassion, mindfulness, and doing good are about defense—hedging against the heavy killing intent in the mind.
A person who only fights hard and attacks without reverence or softness will eventually become a cold machine, ultimately turning against themselves.
Just like a martial arts master:
In youth, they only trained the strongest skills, with too much hostility almost leading to madness. Later, they found peace in the scripture pavilion, practicing meditation and Buddhism, resolving their killing intent, and only then did their martial arts truly reach mastery.
The same applies to trading: you profit by competing in the market, which is inherently sharp and fierce.
A master chooses to do good and accumulate blessings, using kindness to balance the sharpness.
Only knowing how to attack without knowing how to retreat, only understanding killing and fighting without reverence—this path cannot go far.
The market can be sharp, but the heart must be kind.
