Bhagvad Gita

A person in Krsna 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 or happiness. Such a worker is situated in the mode of goodness.
