My world shines into a beam of light, which is loneliness and romance, redemption and abyss. what's the meaning

A beam of light is both redemption and abyss for a person. Because everything has two sides. If it is used well, it will develop well. If you don't make good use of it, you will fall into an endless abyss. Therefore, we expect a beam of light in our life, but we should also make good use of this beam of light to make our life reach its peak.
