The first step of what we call self-realization is to realize what we actually are. This can only be found out in daily life. We cannot find it in a cave. You can sit in a cave for fifteen years, meditate and think you are free of anger, jealousy and everything.But what will you be jealous of in a cave, who will you get angry with ?
There is nobody. Only when you come out of the cave, get into the bus and someone with a high heel steps on your foot, then you know if you are really free of anger. Not in the cave.
