Attachment. One by one. Hostility. Greed. Lamentation, illusion, fear, madness, false prestige, insult, fault-finding, deception, envy, intolerance, passion, bewilderment, hunger, sleep. All of these are enemies. We should struggle to find the spiritual strength to overcome these enemies. That much struggling we have to do. If we don't struggle for that, we'll have to struggle with material nature, which is very hard on the living entity, and causes so much anxiety.
