The greatest evil habit is worldly life. It is called the "Great Addiction". By force of this addiction to worldly life, Paramatman is made to believe that He is an individual, and is compelled to live a worldly life as if in prison. All bad habits can be dropped, but the addiction to mundane life is the most difficult to drop. The wife is dear to her husband so long as she obeys him. The mundane worldly life is called the blindingly dark life. The greatest inticement of Illusion is this mundane life. However great may be one's sorrow, this addiction cannot be dropped. One is greatly lucky if this addiction is dropped. There is only one person who condemns the worldly life, and he is a Saint. Nobody else does that. One does not even think of this earthly life, even if one suffers the utmost difficulties. People try to strengthen their ties with others by speaking to them respectfully and congratulating each other over small things. People compete with each other for earning more honors and status. In this way, they feel that they are happy in life. They act as if this is a respectable bad habit. The God of Death is happy to give you many kinds of bodies and various troubles. Give up the sense of "mine". Know that the body is your enemy. Very few are those who have truly understood. Only those who are lucky enough to receive the blessings of the Guru, who is the Self, can escape from this Illusion by right efforts. All others are bound to the treadmill of life in various incarnations and they make houses of bodies of various shapes and duration.
