sthita-dhir munir ucyate
One who is not disturbed in mind even amidst the threefold miseries or elated when there is happiness, and who is free from attachment, fear and anger, is called a sage of steady mind. Explanation:
This and the next verse are in response to Arjuna's second question in 2.54 about how does a transcendentally situated person speak and what does he speak about? How does a person react to disturbances? The word muni means one who can agitate the mind. A sage or muni is one who has the tendency to mentally speculate. The typical muni is one who uses his mental faculties to disprove past conclusions and establish new ones. However, in this verse, Krishna qualifies the muni as one with a "steady mind." Such a sage has, after exhausting all avenues of mental speculation, finally accepted the supremacy of Krishna as the Personality of Godhead and is fully situated in this consciousness. The term Krishna Consciousness is used to describe such a state. It was first coined by Srila Rupa Goswami in Padyavali as "Krishna Bhakti Rasa Bhavita," or being situated in a state of complete devotion of Krishna. There are three types of miseries in the material world. These are adhyatmika (because of one's own body and mind), adhibhautika (because of other living entities) and adhidaivika (caused by natural disturbances). Every one experiences them at one time or the other. Similarly, every one has at various times experienced some form of enjoyment – even under the most abominable circumstances. Krishna explains that a "sage of steady mind" does not react to either of the two situations: of happiness or distress. Srila Prabhupada elaborates, "Such a fully Krishna conscious person is not at all disturbed by the onslaughts of the threefold miseries, for he accepts all miseries as the mercy of the Lord, thinking himself only worthy of more trouble due to his past misdeeds; and he sees that his miseries, by the grace of the Lord, are minimized to the lowest. Similarly, when he is happy he gives credit to the Lord, thinking himself unworthy of the happiness; he realizes that it is due only to the Lord's grace that he is in such a comfortable condition and able to render better service to the Lord."
