दुःखेष्वनुद्विग्नमनाः सुखेषु विगतस्पृहः।
2.56 That monk is called a man of steady wisdom when his mind is unperturbed in sorrow, he is free from longing for delights, and has gone beyond attachment, fear and anger.
2.56 Even when there are reasons for grief like separation from beloved ones, his mind is not perturbed, i.e., he is not aggrieved. He has no longing to enjoy pleasures, i.e., even though the things which he likes are near him, he has no longing for them. He is free from desire and anger; desire is longing for objects not yet obtained; he is free from this. Fear is affliction produced from the knowledge of the factors which cause separation from the beloved or from meeting with that which is not desirable; he is free from this. Anger is a disturbed state of ones own mind which produces affliction and which is aimed at another sentient being who is the cause of separation from the beloved or of confrontation with what is not desirable. He is free from this. A sage of this sort, who constantly meditates on the self, is said to be of firm wisdom. Then, the next state below this is described:
