Sickness such as fever generated from extreme sorrow at hearing of contempt for Kṛṣṇa by the demons or from separation or other events is called vyādhi or disease, but in this book vyādhi refers to symptoms caused by an emotional state (rather than from disturbance of the dhātus) arising from that separation. In this state, paralysis, slackness of the limbs, heavy breathing, anxiety and fatigue occur.
