What does it mean to find light, chase light and become light?

Chasing the light all the way, getting close to the light, and more importantly, the meaning of emitting light as your own light. Being light means turning yourself into light. The light here is not the meaning of the sun, but an anthropomorphic modification. It is to let yourself shine, constantly improve yourself, constantly contact new people, step into a new level, and be your own light instead of being bathed in the light and heat emitted by others.
