Fortitude, forbearance. (Glossary for the Vahinis)
Titiksha means equanimity in the face of opposites, putting up boldly with duality. Titiksha is not the same as Sahana. Sahana is putting up with something, tolerating it, bearing it, because you have no other choice; having the capacity to overcome it, but yet disregarding it... that is the spiritual discipline; patiently putting up with the external world of duality combined with inner equanimity and peace... that is the path of Liberation. (GV, p. 30)
This is the attitude of forbearance, which refuses to be affected or pained when afflicted with sorrow and loss and the ingratitude and wickedness of others. In fact, one is happy and calm for one knows that these are the results of one’s own actions now recoiling on him, and one looks upon those who caused the misery as friends and well-wishers. One does not retaliate nor does he wish ill of them. One bears all the blows patiently and gladly.
The natural reactions of a person whoever he may be, when someone injures him is to injure in return, when someone causes harm to do harm and when someone insults him to insult back by some means or other. But, this is the characteristic of the Pravritti path - the path of objective involvement. Those who seek the inner path of sublimation and purification, the Nivritti path, have to avoid such reaction. Returning injury for injury, harm for harm or insult for insult only adds to the karmic burden; which has to be endured and eliminated in future lives. This burden is termed Agami or lineal. One cannot escape the task of undergoing the consequences of one’s thought, word and deed in due course. Paying evil for evil can never lighten the weight of karma; it will only become heavier. It might confer immediate relief and contentment, but it cannot but make the person suffer later. Titiksha , therefore instructs man to do good to the person who injures him. (Sutra Vahini, p. 11)
