So as long as you have not attained to desirelessness, as long as you have not renounced desires completely, you will go on taking births and wandering in different bodies. And howsoever different the forms of the body may be, their basic condition is always the same. The ills of the body are the same, regardless whether it’s a bird’s body or man’s. There is no difference in their miseries, because the fundamental misery is only one: the soul becoming confined in the body, the entering of the soul into the prison of body. A prison after all is a prison; it makes no difference whether its walls are circular or angular no matter what you think.
