When, because of self-satisfaction or dislike of excessive labor, a person does not perform his duty in spite of having the energy, he is called lazy. This laziness also is manifested in ecstatic love of Krsna. For example, when some brahmanas were requested by Nanda Maharaj to circumambulate Govardhan Hill, they told him that they were more interested in offering benedictions than in circumambulating Govardhan Hill. This is an instance of laziness caused by self-satisfaction.
Once when Krsna, along with His cowherd boyfriends, was having a mock battle, Subala showed the symptoms of fatigue. Krsna immediately told His other friends, "Subala is feeling too fatigued from mock-fighting with Me. So please do not disturb him any more by inviting him to fight." This is an instance of laziness caused by dislike of excessive labor.
