Lao Tan said, “I was letting my mind wander in the beginning of things.”
“What does this mean?” asked Confucius. Lao Tan said, “It means to attain Perfect Beauty and wander in Perfect Happiness. He who attains Perfect Beauty and wanders in Perfect Happiness may be called the Perfect Man.”
As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
Both the good and the pleasant present themselves to a man. The calm soul examines them well and discriminates. Yes, he prefers the good to the pleasant; but the fool chooses the pleasant out of greed and avarice.
