From then on, the most dedicated ninja in the ninja world was born.

When humans step into the Galactic Era, the ancient art of cultivation thrives once again.

Regardless of the time, cultivation is never obsolete. In the Vajracchedika-prajna-paramita Sutra (a Buddhist scripture), Subhuti (expounder of emptiness) asked Sakyamuni, the founder of Buddhism,

“How does one control his heart to become a buddha?”

This one sentence reveals the essence of cultivation: mastery over one’s heart.

The heart is very powerful, which is the reason why the Monkey King is also called the ‘Heart Monkey’. Everyone’s heart is like a Monkey King; mastering the monkey, one can become something else.

Allow me to demonstrate to you the essence of cultivation.
