BG Chap 18 - Worker in the mode of goodness
A person free from attachment to results and false identity as the doer, devoid of self praise, endowed with courage and enthusiasm, and unperturbed in success and failure, is in the mode of goodness. He tolerates the unavoidable suffering caused by the fruition of old karmas in this present life. He is devoid of happiness when he attains, and devoid of distress when he does not attain, the results of his actions. Equating spiritual consciousness and the mode of goodness, Śrīla Prabhupāda says that a person in Kṛṣṇa consciousness is always transcendental to the material modes of nature. He has no expectations for the result of the work entrusted to him, because he is above false ego and pride. Still, he is always enthusiastic till the completion of such work. He does not worry about the distress undertaken; he is always enthusiastic. He does not care for success or failure; he is equal in both distress and happiness.
