What is good and evil?

At the end of the 19th chaper of the 11th canto of the Srimad Bhagavatam, Krishna answers the questions from his friend Uddhava about what is good and evil.

SB 11.19.40-45: Krishna speaks - "Actual opulence is My own nature as the Personality of Godhead, through which I exhibit the six unlimited opulences. The supreme gain in life is devotional service to Me, and actual education is nullifying the false perception of duality within the soul. Real modesty is to be disgusted with improper activities, and beauty is to possess good qualities such as detachment. Real happiness is to transcend material happiness and unhappiness, and real misery is to be implicated in searching for sex pleasure.

"A wise man is one who knows the process of freedom from bondage, and a fool is one who identifies with his material body and mind. The real path in life is that which leads to Me, and the wrong path is sense gratification, by which consciousness is bewildered. Actual heaven is the predominance of the mode of goodness, whereas hell is the predominance of ignorance.

"I am everyone's true friend, acting as the spiritual master of the entire universe, and one's home is the human body. My dear friend Uddhava, one who is enriched with good qualities is actually said to be rich, and one who is unsatisfied in life is actually poor. A wretched person is one who cannot control his senses, whereas one who is not attached to sense gratification is a real controller. One who attaches himself to sense gratification is the opposite, a slave.

"Thus, Uddhava, I have elucidated all of the matters about which you inquired. There is no need for a more elaborate description of these good and bad qualities, since to constantly see good and bad is itself a bad quality. The best quality is to transcend material good and evil."
