Emperor of the Cosmos
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.
